CommentTIGRFAMs model TIGR02432 describes the family of the N-terminal domain of tRNA(Ile)-lysidine synthetase. This family (TIGR02433) describes a small C-terminal domain of about 50 residues present in about half the members of family TIGR02432,and in no other protein. Characterized examples of tRNA(Ile)-lysidine synthetase from E. coli and Bacillus subtilis both contain this domain.
