Protein
3-oxoacyl-[acyl-carrier-protein] reductase
Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Function
Catalyzes the NADPH-dependent reduction of beta-ketoacyl-ACP substrates to beta-hydroxyacyl-ACP products, the first reductive step in the elongation cycle of fatty acid biosynthesis (Probable). Is capable of reducing acetoacetyl-CoA, but less well than its paralog PhaB (PubMed:26358291).
Similarity
Belongs to the short-chain dehydrogenases/reductases (SDR) family.
