This entry represents a C-terminal domain (CTD) present in TilS ligases proteins, probably implicated in the recognition of the tRNA accetor stem [1]. TilS ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner [1].	Domain
