Comments

FUNCTION: Catalyzes the asymmetric reduction of o-substituted aliphatic and aromatic aldehydes and ketones to an S-enantiomer. Reduces ethyl 4-chloro-3-oxobutanoate to ethyl (S)-4-chloro-3-hydroxybutanoate.
CATALYTIC ACTIVITY: An alcohol + NADP⁺ = an aldehyde + NADPH.
ENZYME REGULATION: Inhibited by quercetin and diphenylhydantoin.
BIOPHYSICOCHEMICAL PROPERTIES:

pH dependence: Optimum pH is 5.5;
Temperature dependence: Optimum temperature is 40 degrees Celsius;
SUBUNIT: Monomer.
SIMILARITY: Belongs to the dihydroflavonol-4-reductase family.
