IUBMB Enzyme Nomenclature


Accepted name: long-chain-fatty-acid—[acyl-carrier-protein] ligase

Reaction: ATP + a long-chain fatty acid + an [acyl-carrier protein] = AMP + diphosphate + a long-chain acyl-[acyl-carrier protein]

Other name(s): acyl-[acyl-carrier-protein] synthetase (ambiguous); acyl-ACP synthetase (ambiguous); stearoyl-ACP synthetase; acyl-acyl carrier protein synthetase (ambiguous); long-chain-fatty-acid:[acyl-carrier-protein] ligase (AMP-forming)

Systematic name: long-chain-fatty-acid:[acyl-carrier protein] ligase (AMP-forming)

Comments: The enzyme ligates long chain fatty acids (with aliphatic chain of 13-22 carbons) to an acyl-carrier protein. Not identical with EC long-chain-fatty-acid—CoA ligase.
