Enzyme Information
| 6.3.4.19 |
tRNA(Ile)-lysidine synthetase.
based on mapping to UniProt O67728
(tRNA(Ile2))-cytidine(34) + L-lysine + ATP = (tRNA(Ile2))-lysidine(34) + AMP + diphosphate + H(2)O.
-!- The bacterial enzyme modifies the wobble base of the CAU anticodon of tRNA(Ile) at the oxo group in position 2 of cytidine(34). -!- This modification determines both codon and amino acid specificities of tRNA(Ile).
