SUMMARY: The hydrolysis of fructose 1,6-bisphosphate to fructose 6phosphate is a key reaction of carbohydrate metabolism. The enzyme that catalyzes this reaction, fructose-1,6-bisphosphatase, appears to be present in all forms of living organisms. Regulation of the enzyme activity, however, occurs by a variety of distinct mechanisms. These include AMP inhibition (most sources), cyclic AMP-dependent phosphorylation (yeast), and light-dependent activation (chloroplast). In the present studies, we have made a comparison of the primary structure of mammalian fructose-1,6-bisphosphatase with the sequence of peptides isolated from the yeast Saccharomyces cerevisiae, Escherichia coli, and spinach chloroplast enzymes. Our results demonstrate a high degree of sequence homology, suggesting a comnon evolutionary origin for all fructose-1,6bisphosphatases. 8 1986 Academic Press. Inc.

MATERIALS AND METHODS: FbPase from baker's yeast (Saccharomyces cerevisiae) was purified to homogeneity by a procedure which consisted of the following steps: Extraction, heating in the presence of fructose 1,6bisphosphate, protamine sulfate treatment, ammonium sulfate precipitation, and phosphocellulose chromatography using substrate elution (12). In vitro phosphorylation of pure yeast FbPase with the catalytic subun= of beefheart CAMP-dependent protein kinase, carboxymethylation of the resulting product, and trypsin digestion of phosphorylatedS-carboxymethylated yeast FbPase was performed as previously described (12). Separation of peptides by reversed-phase HPLC was performed as described in the legend to Figure 1. Escherichia
coli
FbPase was isolated from the Escherichia coli strain Drs. J. Sedivy and D.G. Fraenkel, Hat-yard University). This r. coli strain, carrying the wild type fbp gene in the plasmid pBR322 (16), was grown aerobically for 24-48 h at 37°C in LB broth

plus ampicillin (ZOO pg/ml) and harvested by centrifugation for 15 min at 10,000 g. The pellet was then washed with a buffer (pH 6) containing 10 mM K-malonate, 0.1 mM EDTA, 5 mM MgCl and 1 mM dithiothreitol ("Buffer A"). One gram of cells was ground wi?i 2 g of alumina (Sigma type 305) in a mortar. The paste was extracted with 5 ml of buffer A and the alumina and cell debris were removed by centrifugation. The supernatant was adjusted to pH 6 with 10 mM K-malonate pH 5, and mixed with P-cellulose (Whatman P-11) equilibrated with buffer A to absorb all the FbPase activity. After 30 min of equilibration at 4°C the mixture was allowed to settle, and the supernatant decanted. The P-cellulose suspension was poured into a 0.8 cm-diameter column and washed with buffer A until the absorbance of the eluate at 280 nm was lower than 0.05. The column was then washed with buffer A without MgCl and then with a buffer (pH 6) containing 10 mM K-malonate, 0.1 mM ED?A, 1 mM dithiothreitol, and 30 mM K-phosphate. FbPase was finally eluted with buffer (pH 6) containing 10 mM K-malonate, 0.1 mM EDTA, 1 mM dithiothreitol, 20 mM K-phosphate, and 1 mM fructose 1,6-bisphosphate. The eluent front contained electrophoretically homogeneous enzyme of a specific activity of about 80 U/mg. Purified Escherichia coli fructose-1,6-bisphosphatase was carboxymethylated by the method of-stfield et al. (17), with minor modifications (18). Digestion of the S-carboxymethylated protein with trypsin (TRTPCK from Cooper/Worthington) was performed for 6 h at 37'C in 50 mM N-ethylmorpholine-acetate buffer (pH 8.5) at a 5O:l w/w ratio of FbPase to trypsin. The reaction products were separated by reversed-phase HPLC. Automated microsequencing of peptides (0.5-1.5 nmol) was performed in an Applied Biosystems 470A gas-phase protein sequencer using the standard sequencing program and the reagents provided by the manufacturer. The phenylthiohydantoin derivatives of amino acids liberated after each degradation cycle were identified and quantitated as such by HPLC using slight modifications of previously published methods (19,20). The analyses were performed with a Waters Model 840 system equipped with an IBM octadecyl column (4.6 x 250 mm). Repetitive yields were at least 90%. Amino acid analyses were performed as described by Bidlingmeyer Pep--et al. (21). tides (100-500 pmol) were hydrolyzed in vapor of 6 N HCl for 22 h at 110’. The liberated amino acids were reacted with phenylisothiocyanate and the resulting derivatives analyzed by reversed-phase HPLC on a Waters 840 system equipped with a Waters Pica-Tag column.
