DNA CLONE ENCODING AN ETHYLENE-FORMING ENZYME, CONSTRUCTS, PLANT CELLS AND PLANTS BASED THEREON Bird Cohn R; Ray John; Schuch Wolfgang Bra&tell, UNITED KINGDOM assigned to Zeneca Limited PCT No. PCT/GB91/02272 Sec. 371 Date Aug. 2, 1993 Sec. 102(e) Date Aug. 2, 1993 PCT Filed Dec. 19, 1991 PCT Pub. No. WO92/11371 PCT Pub. Date Jul. 9, 1992. DNA clones, e.g. M13-1, comprising at least part of a gene derived from melon that encodes ethylene-forming enzyme. Such clones may comprise DNA constructs including plant promoters capable of expressing RNA in plant cells. Such constructs may be used to inhibit production of ethylene-forming enzyme in transformed plants, and thereby to produce slower-ripening fruit, particularly melons. The clones may be obtained by PCR using specific oligo-nucleotide primers.

PATENT ABSTRACTS
This invention is directed to the acetyl-CoA hydrolase enzyme of yeast and to a method for purifying ace@-CoA hydrolase. The enzyme has a molecular weight of about 64,000 daltons and an enzyme activity of greater than 20 units wherein one unit of acetyl CoA hydrolase activity is defined as the amount of enzyme able to inhibit 1 unit of acetyltransferase activity and 1 unit of acetyltransferase activity is defined as the amount of enzyme needed to transfer 1 pmol of (3H) acetyl group from (3H) acetyl coenzyme A to ACTH (l-24) in the acetyltransferase standard enzyme assay under standard conditions. The invention is further directed to the glucose-repressible promoter which regulates the expression of the acetyl-CoA hydrolase gene in yeast, to vectors incorporating this promoter and to host cells transformed with such vectors.

5492813 MUTEINS
OF
BETA-GALACTOSIDASE FRAGMENTS HAVING INCREASED
ACTIVITY
Eisenbeis Scott J; Boguslawski Sophie J; Krevolin Mark; Ledden David J Indianapolis, IN, UNITED STATES assigned to Boehringer Mannheim Corporation Muteins of enzyme acceptor polypeptide fragments of beta-galactosidase are provided which exhibit substantially increased kinetic complementation activity with no significant loss in stability. A preferred enzyme acceptor fragment has an amino acid other than cysteine located at position 500 of the natural sequence. An especially preferred substitution is serine or valine. Other preferred muteins have an amino acid other than methionine located at position 443, with leucine being especially preferred, or an amino acid other than cysteine at position 76, with leucine being an especially preferred substitution. Also provided are methods for producing the novel muteins, reagent compositions comprising the novel muteins, and immunoassay methods for determining an analyte in which the novel mutein recombines with an enzyme donor polypeptide fragment to form enzymatically active beta-galactosidase. 5492822 METHOD FOR RECOVERING 100,000 DALTON PURIFIED MOLECULAR WEIGHT FRACTION OF HUMAN PANCREATIC CHOLESTEROL ESTERASE Lange Louis G; Spilburg Curtis A; St Louis, MO, Kinnunen Paula M
