Enzyme Commission Primary Name: enoyl-[acyl-carrier-protein] reductase (NADH)
Enzyme Commission Synonyms: enoyl-[acyl carrier protein] reductase, enoyl-ACP reductase, NADH-enoyl acyl carrier protein reductase, NADH-specific enoyl-ACP reductase, acyl-[acyl-carrier-protein]:NAD+ oxidoreductase, fabI (gene name), inhA (gene name)
Enzyme Commission Summary:
The enzyme catalyses an essential step in fatty acid biosynthesis, the reduction of the 2,3-double bond in enoyl-acyl-[acyl-carrier-protein] derivatives of the elongating fatty acid moiety. The enzyme from the bacterium Escherichia coli accepts substrates with carbon chain length from 4 to 18 [Yu11]. The enzyme from the bacterium Mycobacterium tuberculosis prefers substrates with carbon chain length from 12-24 carbons [Quemard95, Rozwarski99].
