Function
function
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.
Catalytic activity
- cytidine34 in tRNA(Ile2) + L-lysine + ATP = lysidine34 in tRNA(Ile2) + AMP + diphosphate + H+
