Protein
Enoyl-[acyl-carrier-protein] reductase [NADH] FabI
Gene
fabI, aq_1552
Organism
Aquifex aeolicus (strain VF5)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

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 By similarity.

Catalytic activityi

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