DE   A-factor type gamma-butyrolactone 1'-reductase (1S-forming).
CA   a (3R,4R)-3-[(1S)-1-hydroxyalkyl]-4-(hydroxymethyl)oxolan-2-one + NADP(+)
CA   = a (3R,4R)-3-alkanoyl-4-(hydroxymethyl)oxolan-2-one + H(+) + NADPH.
CC   -!- The enzyme, which is found in bacteria that produce virginiae-
CC       butanolide (VB) type gamma-butyrolactone autoregulators, reduces its
CC       substrate stereospecifically, forming a hydroxyl group in the (S)
CC       configuration.
