Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). Involved in the elongation cycle of fatty acid which are used in the lipid metabolism and in the biotin biosynthesis By similarity.

Catalytic activity

Acyl-[acyl-carrier-protein] + NAD+ = trans-2,3-dehydroacyl-[acyl-carrier-protein] + NADH.

Pathway

Lipid metabolism; fatty acid biosynthesis.

Cofactor biosynthesis; biotin biosynthesis.

Subunit structure

Homotetramer By similarity.

Sequence similarities

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