1. INTRODUCTION

The aim of this article is to provide a list of proteins having known macromolecular parameters, with particular emphasis on isoelectric points (pl) and molecular weights (M-W.). The new updated revision of the classical tabfes of D~FI~ and Klotz’ now has more than 500 entries, each complete with the native molecular weight of the macromolecule, as well as its subunit number and M.W. For each entry, these workers also list the source and, when applicable, the organ of origin. This is very important, since lack of this information in previous tables has generated confusion. The main aim of DarnaH and Klot$ was to tabulate proteins having a known quaternary structure. Similar tables have been published by Klein$. However, there is no literature compilation of information on the charge (pl) as well as on the size (M.W.) of proteins. Yet, the pl of a protein is a very important parameter, and its knowledge is very important for the proper use of several techniques, such as disc electrophoresis, isotachophoresis, isoelectric focusing, ion-excharzgechromatography and even ammonium sulphate fractionation. Until recently, the literature data on pf values of proteins were scanty and even contradictory. With the advent of isoelectric focusing34, pf data for proteins have been rapidly expanding, to an extent which justifies their collection in- a tabie. Thus, the main emphasis here is on the availability and collection of proteiir pl values. When available, we also report their M.W. values and quaternary structure. The coribined knowiedge of these two parameters makes possible the macromoIecuIar zapping of proteins’. Most proteins, in fact, are urtequivoeally determined by values of their pf and M.W. (except, perhaps,

for very close genetic variants of a protein, such as human haemoglobin).

Many of the entries in our tables, which lack data on M.W. and subunit structure, can be found in the tables of Damall and Klotzl. However, for the same protein the source and/or the organ may be difierent; therefore we decided not to report such data. Since most of the proteins reported display microheterogeneity, we have marked the main components with an asterisk when this information was available or could be deduced from graphs or tables. In addition, we also report not only the source and the organ, but also the intracellular Iocation, in the case of isozymes displaying different properties in different subcellular compartments. Unfortunately, there is quite a degree of uncertainty as to the temperature of pH measurement. This is quite an important parameter when defining the p1 of a protein, since acid-base equilibria are temperature dependent and a pL of a protein, if quoted without the temperature of measurement, is per se ambiguous and lacks an exact physicochemical signticance. Some workers never report the temperature of pH measurement. Most workers simply refer to measurements performed at room temperature, which, unfortunately, is not unequivocally determined_ Only a few workers have made pH measurements at a precise temperature, in a thermostatted vessel. Since the way in which a pH measurement is made is of utmost importance in def%riug PI, we summarize here the different techniques used, either in liquid or in gel media. (A) Meamremem

of pH in isoelectric focusing

The pI of a protein determined by isoelectric focusing (IEF) also represents its isoionic point in the absence of complex-forming ionss. By detiition, the isoionic point is a measure of the intrinsic acidity of a pure protein, as it is de&red as that pH which does not change on addition of a small amount of pure protein9. This definition is also applicable to a protein analyzed by LEF, as the pH of the isoelectric zone does not alter on addition of more protein. it should be remembered that pI values estimated by IEF are temperature dependent and usually decrease with increasing temperature6. The difference in pI for the same protein, measured at 25 and at 4”, could be as high as 0.5 pH units, the higher value being obtained at the lower temperature. This difference is usually more pronounced in alkaline regions, and when a protein has a pI value close to the pK of some of its functional groups. Unfortunately, when given a pE value for a protein at a certain temperature it is difficult to extrapolate this value to another temperature, since the temperature coefficient, dpI/d7’, can vary from protein to protein. Thus Bours’*, by measuring the pI values of @-lactoglobulin A and B at 4 and 25”, found a value of dpI/dT of -(0.9 + 0.2). IO-” pH unit per degree. On the other hand, measurements of pl at 4 and 25” for carbonic anhydrase have given a dpI/dT value of -(l-3 f 0.2). lo-’ pH unit per degree. In the case of myogiobin I*, the temperature coefficient is as high as - 1.7 - lo-’ pH unit per degree. Ideally, pH measurements should be made at the same temperature used during the IEF separation, since in IEF the temperature coefficient, dpT/dT, refers to the corresponding carrier ampholytes rather than to the protein contained in a given fraction. In fact, at the usual concentration of Ampholine (I%), the buffering capacity of the carrier ampholytes in the isoelectric state will normally be su&ient to permit them to dictate the pH even in the presence of as much as 1 oA of proteir&=.

means that the pH vatue assigned to the concentration maximum of 2 focused protein at a temperature different from the IEF temperature will refer to the corresponding different protolytic ampholyte fraction rather than to the protein ls_ Furthermore, groups are known to display widely different degrees of temperature dependence in their dissociation constants (as a consequence of Iarge differences in their standard heats of ionization)l’. Thus, once a protein has been focused at 4”, a pd measurement made at 20 or at 25” may not represent the true pI of the protein or the pE of the Ampholine molecules surrounding it. In addition, pH measurements can also be affected by the presence of solutes such as glycerol and sucrose, which are common!y used in IEF. As sucrose lowers the dieiectric constant of the solvent and this, in turn, causes the pK values of amino acids to increase15, it can be expected that the p! value of a given protein is increased on increasmg the concentration of sucrose. When TEF is performed in the presence of urea, it should be noted that urea appreciably decreases the activity coefficient of hydrogen ions, resulting in apparently higher pK and pl values of the carrier amphofytes. Correction factors should therefore be used for pl determinations of proteins in ureax6_ (B) pH meczswements

afrer IEF in density

grdients

En preparative IEF in liquid support media, combined UV and pH readings of a!! of the collected fractions can be a lengthy and cumbersome procedure. To overcome this, Jonsson et cr1.l’ automated the analysis of column contents by pumping them at a constant rate through series-coupled flow cells, one cell for the recording of pH and the other cell for the determination of UV absorbance. This set-up, however, presented some difficulties in pH determination, which are discussed in detail by these workers l’. LMore recently, Secchi Is described a modification of this technique, which appears to overcome many of the problems. A combined glass electrode (ingold Type 401-M7, provided with a Sow vessel and water cooling jacket) is coupled ir, series with the UV Sow cell of an LKB Uvicord If. In this case, the UV signal and pH readings are fed, via a control unit, to the same galvanometric recorder used for the UV readings (LKB 6500). Since the volume lag between the pH and UV cells is only 0.35 m!, accurate and simultaneous pH and UV readings are obtained on the same recorder chart. Moreover, since the pH cell is thermostatted, pH readings are made at the temperature of the focusing column. Another advantage of flow systems is that absorption of carbon dioxide from the air, which might aKer.t pI readings by lowering the pH of the solution, especially in alkaline regions, is 2~ oided. A simiiar set-up was reported by Strongin et al.19, who brdt a pH flow cell in Ferspex with Type K-401 and Type GK 2320~ pH electrodes. from Radiometer A/S. When using Aow cells, the peristaltic pump should be attached after the cells, in order to prevent leakage of potassium chloride from the e!ectrlJdes and to keep the Sow-rate as low as possible (to avoid pressure on the glass membl ane of the electrode, which could alter the pH readings). Alternatively, for measurem-nt of the pH course in a micro-column, where fractions of only 60 ~1 are colkcted, FredrikssorGO described the use of a Radiometer micro glass electrode, in which the pH-sensitive membrane is shsped as a horizontal capillary. The capillary can be filled, via a vertical poiyethylene tube, simp!y by suction. A volume as sma!! as 20 p! is sufficient for pH reading. Values correct to within O-O! pH unit have been reported.

When performing IEF in solid support media, it is convenient to be able to measure directly the pH gradient along the gel length. For flat gels, a surface electrode may be used with a coplanar glass reference electrode- haviug either a flat face or a spear tip. In either case, it is advisable to have the probes of both electrodes as close as possible to minimize errors due to differences in conductivity throughout the gel. One of the first electrodes developed for pM measurements on gel surfaces is the antimony micro-electrode, in conjunction with a calomel reference electrode, reported by Beeley et al. 2L. This electrode, which was originally developed by Kleinberg= to measure the pH of dental plaques, has a spear tip of 1 mm in diameter. Measlltements are made by placing the gel over a sheet of graph paper, pressing the reference electrode at any position along the gel length and scanning at regular intervals with the antimony micro-electrode. Where the pII reading has been made, the gel is marked by serration with a scalpel blade. This allows a much greater accuracy in the determination of pI by interpolation on a graph of PI-I ve~stlsprotein position in the gel. With the antimony electrode, readings of electromotive force are obtained on the millivolt scale and are converted into units of pH by means of an appropriate calibration graph. This type of electrode might be better standardized against Ampholine solutions, which in turn are calibrated against standard bufferP_ One important property of the antimony micro-electrode, in contrast to very small glass electrodes, is its rapid equilibration time (less than 10 set), even at low temperatures, which makes it very attractive for use at 4”. However, one disadvantage of this electrode is its low reproducibility, given by Beeley et al,” as < O-25 pH units, in comparison with the resolution of 0.02 pH units, and even less, afforded by IEF. Alternatively, on gel slabs, the pH can be measured directly on the gel surface with a flat membrane electrode, such as LOT Type 403-3U-MS frcm Ingold. However, since this electrode has a high sul-face area (membrane diameter, S mm), DrysdaIe** (in collaboration with Ingold Inc., Lexington, Mass., U.S.A.) has developed a flat membrane micro-electrode. This h-shaped electrode contains the reference unit in one arm, and the measuring membrane in a parallel arm. The two electrodes are coplanar, and are on@ 3 mm apart in order to offset variations in conductivity along the gel. The pH membrane has a diameter of 2.5 mm. This allows accurate pH measurements over a small surface; however, due to the high impedance of the small glass membrane, this electrode is practically of no use at low temperatures, since the response times are extremely long. -In order to overcome the problems connected with the use of surface electrodes, we have devised a simple method for accurate pH measurements in gel slabs, using a standard combination micro-electrode. The gel slab is focused over plastic graph paper placed on the coolm g block of an LKB Multiphor 2117 apparatus, thermostatted at 4”. At the end of the experiment, 22 OF 23 gel segments are cut from the side of the gel, at 0.5-cm intervals. Simultaneously, a l-2-mm diameter hole is bored in the gel (with the help of a gel puncher for immunodi&tsion and of a suction pump) in a zone corresponding to the middle of the 05cm gel segment removed for pH measurement. Since this operation is made on the cooling block, and requires only a few minutes, no appreciable diffusions of the protein zones takes place. The rectangular gel segments removed are eluted in small test-tubes with 0.3 ml of i0 mv

KCZ. Since the combination micro-electrode, with a saturated solution of KC1 and buffers, is kept in the cold room (connected to the electronic control unit outside by a cabfe passing through the wall), accurate and reproducible pH measurements are obtained from the gel eluates at the focusing temperature. The pH profile can be easily superimposed on the stained gel slab with the aid of the 22 or 23 holes punched in it. [D)

covering the pH range of interest. Ideally, these pH markers should be coloured proteins or dyes. fn the case of protein markers, they should not be heterogeneous, or at least have a major, easily identificable, band in order to avoid confusion in pH assessments. Studies on the use of pH markers have been reported by ConwqJacobs and Lewin=, Nakbleb et al. 26, Bours’O and Radol$‘. We have listed the&ost coriunon protein and dye markers in Table 1. This table will be followed by.: tf;e .__ com@&ion of data on pI and M.W. values of proteins. En these tables, the most accessible references are given for each entry;. they do not necessarily indicate the source most deserving of credit for the macromolecular parameters given. Some references might have been overlooked. We would appreciaEe comments from other laboratories on missing references and data or on possible errors in these tables. We hope that this compilation wiIi prove useful for teaching and research purposes. 2. ACKNOWLEDGEMENT

This project was supported by resexch grants CT74.00255.04 and No. 75. 00686.115.4756 from Consiglio Nazionale delle Ricerche (C-N-R.), Italy. 3. SUMMARY

Proteins with known isoelectric points ‘@Z), as determined by isoelectric focusing, have been tabuIated. When availabie, the native moIecuIar weight as well as subunit molecular weight and stoichiometry have been reported. For each entry, the source and, when applicable, the organ of origin and/or subcelfular location are given. The pZ values are listed together wit& the respective temperature of pH measurement. Moreover, in the case of proteins displaying microheterogeneity, the major components have been indicated. The table lists a total of approximately 800 pZ values.
