This domain is found in 3-methyl-D-ornithine--L-lysine ligase from Methanosarcina barkeri (PylC) and similar sequences from prokaryotes. PylC is required for the biosynthesis of pyrrolysine. This ATP-grasp enzyme is composed of three domains. This entry represents the N-terminal domain, which is composed of a central four-stranded beta-sheet that is faced on both sides by two helices. It shows an adenine binding pocket that has not been observed in any homologous structure determined before [1].	Domain
