We determined the amino acid sequences of two keto ester reductases (YKER-V and -VI) purified from a cell-free extract of Saccharomyces cerevisiae. The N-terminal and internal amino acid sequences of YKER-VI (AcKR) were in agreement with the sequence of hypothetical 36.4-kDa protein (S. cerevisiae chromosome X reading frame ORF YJR105w) in yeast. The N-terminal amino acid sequence of YKER-V was also identical with that of the hypothetical protein coded by yeast chromosome XIV or II. These results suggested that two hypothetical proteins were expressed as keto ester reductases in yeast cells.
