Protein
Enoyl-[acyl-carrier-protein] reductase [NADH] FabI
Gene
fabI, BUsg_255
Organism
Buchnera aphidicola subsp. Schizaphis graminum (strain Sg)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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 activityi

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