description: 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 [[cite:PUB00034489]]. These proteins belong to the PP-loop
  superfamily [[cite:PUB00014303]].
