2.7.1.169	ATP	the electron density for the adenosine moiety of ATP is very weak, which most likely relates to its broad nucleotide specificity. The triphosphate moiety of ATP is surrounded by the lycine-rich loop of motif II (P96NGYGFGNSAG106). The magnesium ion can interact with oxygen atoms of beta- and gamma-phosphates, and with the O5' atom of ATP which bridges the adenosine and the triphosphate groups	762353
