General annotation (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 By similarity. HAMAP-Rule MF_01161

Catalytic activity

IMP + diphosphate = hypoxanthine + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP-Rule MF_01161

GMP + diphosphate = guanine + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP-Rule MF_01161

(tRNA(Ile2))-cytidine34 + L-lysine + ATP = (tRNA(Ile2))-lysidine34 + AMP + diphosphate + H2O. HAMAP-Rule MF_01161

Cofactor

Binds 2 magnesium ions per subunit. One of the ions does not make direct protein contacts By similarity.

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_01161.

Domain

The N-terminal region contains the highly conserved SGGXDS motif, predicted to be a P-loop motif involved in ATP binding. HAMAP-Rule MF_01161

Sequence similarities

In the N-terminal section; belongs to the tRNA(Ile)-lysidine synthase family.

In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
