CC   -!- FUNCTION: Catalyzes the reduction of a carbon-carbon double bond in an
CC       enoyl moiety that is covalently linked to an acyl carrier protein
CC       (ACP). Involved in the elongation cycle of fatty acid which are used in
CC       the lipid metabolism (By similarity). {ECO:0000250}.
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   -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC       family. FabI subfamily. {ECO:0000305}.
