CC   -!- FUNCTION: Ligates lysine onto the cytidine present at position 34 of
CC       the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an
CC       ATP-dependent manner. Cytidine is converted to lysidine, thus changing
CC       the amino acid specificity of the tRNA from methionine to isoleucine.
CC       {ECO:0000255|HAMAP-Rule:MF_01161}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + cytidine(34) in tRNA(Ile2) + L-lysine = AMP +
CC         diphosphate + H(+) + lysidine(34) in tRNA(Ile2);

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01161}.
CC   -!- DOMAIN: The N-terminal region contains the highly conserved SGGXDS
CC       motif, predicted to be a P-loop motif involved in ATP binding.
CC   -!- SIMILARITY: Belongs to the tRNA(Ile)-lysidine synthase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01161}.
