title: Purification and properties of a carbonyl reductase useful for production of ethyl (S)-4-chloro-3-hydroxybutanoate from Kluyveromyces lactis.
abstract: A novel carbonyl reductase (KLCR1) that reduced ethyl 4-chloroacetoacetate (ECAA) to synthesize ethyl (S)-4-chloro-3-hydroxybutanoate ((S)-ECHB) was purified from Kluyveromyces lactis. KLCR1 catalyzed the NADPH-dependent reduction of ECAA enantioselectively but not the oxidation of (S)-ECHB. From partial amino acid sequences, KLCR1 was suggested to be an alpha subunit of fatty acid synthase (FAS) but did not have FAS activity.
