CC -!- FUNCTION: Involved in the final reduction of the elongation cycle of
CC fatty acid synthesis (FAS II). Catalyzes the reduction of a carbon-
CC carbon double bond in an enoyl moiety that is covalently linked to an
CC acyl carrier protein (ACP). {ECO:0000256|HAMAP-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:0000256|ARBA:ARBA00001615};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2,3-saturated acyl-[ACP] + NAD(+) = a (2E)-enoyl-[ACP] +
CC H(+) + NADH; Xref=Rhea:RHEA:10240, Rhea:RHEA-COMP:9925, Rhea:RHEA-
CC COMP:9926, ChEBI:CHEBI:15378, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:78784, ChEBI:CHEBI:78785; EC=1.3.1.9;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01838};
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis. {ECO:0000256|HAMAP-
CC Rule:MF_01838}.
CC -!- SUBUNIT: Monomer. {ECO:0000256|ARBA:ARBA00011245, ECO:0000256|HAMAP-
CC Rule:MF_01838}.
CC -!- SIMILARITY: Belongs to the TER reductase family. {ECO:0000256|HAMAP-
CC Rule:MF_01838}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
