General annotation (Comments)

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 By similarity.

Catalytic activity

(3R)-3-hydroxyacyl-[acyl-carrier-protein] + NADP+ = 3-oxoacyl-[acyl-carrier-protein] + NADPH.

Pathway

Lipid metabolism; fatty acid biosynthesis.

Subunit structure

Homotetramer. Ref.2

Sequence similarities

Belongs to the short-chain dehydrogenases/reductases (SDR) family.
