Abstract: Mutants of 2,5-diketo-D-gluconic acid reductase A, an enzyme used to produce 2-keto-L-gulonic acid, a precursor of ascorbic acid (vitamin C) are prepared by site-directed mutagenesis. These mutants have increased catalytic activity, increased expression levels, and/or enhanced temperature stability.

Abstract: A composition of matter derived from hematophagous leech comprising specified purified amino acid sequences represented by the general formula:CXXXRGDXXXXC(Seq. ID No. 11)and capable of functioning as an antithrombotic by inhibiting the binding of fibrinogen to the platelet glycoprotein II.sub.b III.sub.a (GP II.sub.b III.sub.a), a fibrinogen receptor. Methods for the purification of amino acid sequences from leeches, and particularly from leeches of the genus Macrobdella and Placobdella. are provided. Isolated nucleic acid sequences encoding these amino acid sequences; an expression vector containing the isolated nucleic acid; and a cell containing the expression vector are also described. A process for chemical synthesis of the amino acid sequences and a method for reducing platelet aggregation in a mammal by administering a composition containing the amino acid sequences to the mammal in a pharmaceutically effective amount are provided.

Abstract: In recombinant microorganisms which were rendered capable of converting 2,5-diketo-D-gluconic acid (2,5-DKG) to 2-keto-L-gulonic acid (2-KLG) by transfer of genetic material, the secondary metabolites and metabolic pathways leading to the metabolic diversion of 2-KLG and 2,5-DKG were determined, and the diversion of 2-KLG to L-iodonic acid (IA) or of 2,5-DKG to 5-keto-D-gluconate (5-KDH) was blocked.

Abstract: Recombinant plasmids containing the gene encoding 2,5-diketogluconic acid reductase are prepared and used to transform microorganisms. 2,5,DKG reductase is expressed by the microorganisms.
