Purification and characterization of alpha-keto amide reductase from Saccharomyces cerevisiae

Biosci Biotechnol Biochem. 2004 Nov;68(11):2306-12. doi: 10.1271/bbb.68.2306.

Abstract

An NADPH-dependent alpha-keto amide reductase was purified from Saccharomyces cerevisiae. The molecular mass of the native enzyme was estimated to be 33 and 36 kDa by gel filtration chromatography and SDS-polyacrylamide gel electrophoresis, respectively. The purified enzyme showed a reducing activity not only for aromatic alpha-keto amides but also for aliphatic and aromatic alpha-keto esters. The internal sequence of the enzyme was identical with that of a hypothetical protein (ORF YDL 124w) coded by yeast chromosome IV.
