Structural snapshots for the conformation-dependent catalysis by human medium-chain acyl-coenzyme A synthetase ACSM2A.
Acyl-CoA synthetases belong to the superfamily of adenylate-forming enzymes, and catalyze the two-step activation of fatty acids or carboxylate-containing xenobiotics. The carboxylate substrate first reacts with ATP to form an acyl-adenylate intermediate, which then reacts with CoA to produce an acyl-CoA ester. Here, we report the first crystal structure of a medium-chain acyl-CoA synthetase ACSM2A, in a series of substrate/product/cofactor complexes central to the catalytic mechanism. We obs...Expand abstract
