Comments
[?]
| 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 | Reaction=ATP + cytidine(34) in tRNA(Ile2) + L-lysine = AMP + diphosphate + H(+) + lysidine(34) in tRNA(Ile2); Xref=Rhea:RHEA:43744, Rhea:RHEA-COMP:10625, Rhea:RHEA-COMP:10670, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:32551, ChEBI:CHEBI:33019, ChEBI:CHEBI:82748, ChEBI:CHEBI:83665, ChEBI:CHEBI:456215; EC=6.3.4.19; |

| SUBCELLULAR LOCATION | Cytoplasm. |
| else case <OG:Chloroplast> | |
| SUBCELLULAR LOCATION | Plastid, chloroplast. |
| end case | |
| case <FT:1> | |
| DOMAIN | The N-terminal region contains the highly conserved SGGXDS motif, predicted to be a P-loop motif involved in ATP binding. |
| end case | |
| SIMILARITY | Belongs to the tRNA(Ile)-lysidine synthase family. |
