EC 6.2.1.2     
Accepted name: medium-chain acyl-CoA ligase
Reaction: ATP + a medium-chain fatty acid + CoA = AMP + diphosphate + a medium-chain acyl-CoA
Other name(s): fadK (gene name); lvaE (gene name); butyryl-CoA synthetase; fatty acid thiokinase (medium chain); acyl-activating enzyme; fatty acid elongase; fatty acid activating enzyme; fatty acyl coenzyme A synthetase; butyrate—CoA ligase; butyryl-coenzyme A synthetase; L-(+)-3-hydroxybutyryl CoA ligase; short-chain acyl-CoA synthetase; medium-chain acyl-CoA synthetase; butanoate:CoA ligase (AMP-forming)
Systematic name: medium-chain fatty acid:CoA ligase (AMP-forming)
Comments: Acts on fatty acids from C4 to C11 and on the corresponding 3-hydroxy and 2,3- or 3,4-unsaturated acids. The enzyme from the bacterium Pseudomonas putida also acts on 4-oxo and 4-hydroxy derivatives.
