This entry represents the preATP-grasp domain found at the N-terminal of archaeal LysX, ArgX and similar proteins. LysX catalyses the ATP-dependent formation of a covalent bond between the amino group of alpha-aminoadipate (AAA) and the gamma-carboxyl group of the C-terminal glutamate residue in LysW [1,2]. ArgX catalyses the ATP-dependent formation of a covalent bond between the amino group of glutamate and the gamma-carboxyl group of the C-terminal glutamate residue in LysW [2].	Domain
