Protein existenceInferred from homology

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 By similarity.

Miscellaneous

Calcium ions stabilize the structure, and may inhibit FabG activity by obstructing access to the active site By similarity.

Sequence similarities

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