The structure of tRNA(Ile)-lysidine synthetase consists of an N-terminal dinucleotide-binding fold domain (NTD), and a C-terminal globular domain (CTD). The structure of the NTD closely resembles that of a P-loop "N-type" ATP pyrophosphatase [2]. These proteins belong to the PP-loop superfamily [1].	Domain
