Taxonomic identifier

42862 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia › spotted fever group

Protein attributes

Sequence length	430 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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.
Subcellular location	CytoplasmProbable.
Domain	The N-terminal region contains the highly conserved SGGXDS motif, predicted to be a P-loop motif involved in ATP binding. HAMAP MF_01161
Sequence similarities	Belongs to the tRNA(Ile)-lysidine synthase family.
