RL   Submitted (OCT-2005) to the EMBL/GenBank/DDBJ databases.
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:0000255|HAMAP-Rule:MF_01838}.
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: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}.
