Protein attributes

Sequence length275 AA.
Sequence statusComplete.
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 By similarity.

Catalytic activity

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

Pathway

Lipid metabolism; fatty acid biosynthesis.

Subunit structure

Homotetramer By similarity.

Sequence similarities

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