CC -!- FUNCTION: Catalyzes the NADPH-dependent reduction of beta-ketoacyl-ACP
CC substrates to beta-hydroxyacyl-ACP products, the first reductive step
CC in the elongation cycle of fatty acid biosynthesis. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a (3R)-hydroxyacyl-[ACP] + NADP(+) = a 3-oxoacyl-[ACP] + H(+)
CC + NADPH; Xref=Rhea:RHEA:17397, Rhea:RHEA-COMP:9916, Rhea:RHEA-
CC COMP:9945, ChEBI:CHEBI:15378, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC ChEBI:CHEBI:78776, ChEBI:CHEBI:78827; EC=1.1.1.100;
CC -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. {ECO:0000305}.
