Comments
Comment typeDescription
Catalytic ActivityAcetyl-CoA + malonyl-[acyl-carrier-protein] = acetoacetyl-[acyl-carrier-protein] + CoA + CO(2).
FunctionCatalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. KAS III catalyzes the first condensation reaction which initiates fatty acid synthesis and may therefore play a role in governing the total rate of fatty acid production. Possesses both acetoacetyl-ACP synthase and acetyl transacylase activities (By similarity). {ECO:0000250}.
PathwayLipid metabolism; fatty acid biosynthesis.
Sequence CautionSequence=AAD43621.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305}; Sequence=AAF19534.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
SimilarityBelongs to the FabH family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast.
