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 and in the biotin biosynthesis (By similarity).
CC {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 -!- PATHWAY: Cofactor biosynthesis; biotin biosynthesis.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- MISCELLANEOUS: The antibiotic diazaborine interferes with the activity
CC by binding to the protein. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. FabI subfamily. {ECO:0000305}.
