ATP_bind_3

 ATP_bind_3
PFAM accession number:PF01171
Interpro abstract (IPR011063):

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 [ (PUBMED:15894617) ]. tRNA(Ile)-lysidine and 2-thiocytidine synthase both belong to the PP-loop superfamily [ (PUBMED:7731953) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry ATP_bind_3
