CC   -!- FUNCTION: Involved in the fatty acid synthesis (FAS II). Catalyzes the
CC       reduction of a carbon-carbon double bond in an enoyl moiety that is
CC       covalently linked to a coenzyme A (CoA). {ECO:0000255|HAMAP-
CC       Rule:MF_01838}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 2,3-saturated acyl-CoA + NAD(+) = a (2E)-enoyl-CoA + H(+) +
CC         NADH; Xref=Rhea:RHEA:18177, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540,
CC         ChEBI:CHEBI:57945, ChEBI:CHEBI:58856, ChEBI:CHEBI:65111; EC=1.3.1.44;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01838};
CC   -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis. {ECO:0000255|HAMAP-
CC       Rule:MF_01838}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01838}.
CC   -!- SIMILARITY: Belongs to the TER reductase family. {ECO:0000255|HAMAP-
CC       Rule:MF_01838}.
