CC   -!- FUNCTION: Involved in the aerobic and anaerobic degradation of long-
CC       chain fatty acids via beta-oxidation cycle. Catalyzes the formation of
CC       3-oxoacyl-CoA from enoyl-CoA via L-3-hydroxyacyl-CoA. It can also use
CC       D-3-hydroxyacyl-CoA and cis-3-enoyl-CoA as substrate.
CC       {ECO:0000255|HAMAP-Rule:MF_01621}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a (3S)-3-hydroxyacyl-CoA + NAD(+) = a 3-oxoacyl-CoA + H(+) +
