Coordination of α-phosphate by positively charged residues in different classes of adenylate-forming enzymes. In each member at least one positively charged residue, as lysine, argentine or histidine is present. Acetyl-CoA synthetase (2p2f) and Japanese firefly luciferase (2d1q) are class I, human tryptophanyl-tRNA synthetase (2qui) and lysyl-tRNA synthetase (1e24) are class II, AcsD (2wo2) and AlcC (alcc) are class III adenylate-forming enzymes. ATP colored in grey and shown in line representation is ATP of AcsD.
