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:0000256|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 Evidence={ECO:0000256|ARBA:ARBA00000047, ECO:0000256|HAMAP-
CC Rule:MF_01161};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01161}.
CC Plastid, chloroplast {ECO:0000256|ARBA:ARBA00004229}.
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 {ECO:0000256|HAMAP-Rule:MF_01161}.
CC -!- SIMILARITY: Belongs to the tRNA(Ile)-lysidine synthase family.
CC {ECO:0000256|HAMAP-Rule:MF_01161}.
