tRNA(Ile)-lysidine synthase

UniProtKB accession:  P52097

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine. This enzyme is essential for viability.
