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(+) +

CC -!- PATHWAY: Lipid metabolism; fatty acid beta-oxidation.
CC {ECO:0000255|HAMAP-Rule:MF_01621}.
CC -!- SUBUNIT: Heterotetramer of two alpha chains (FadB) and two beta chains
CC (FadA). {ECO:0000255|HAMAP-Rule:MF_01621}.
