Protein

tRNA(Ile)-lysidine synthase

Gene

tilS

Organism
Tropheryma whipplei (strain TW08/27) (Whipple's bacillus)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

(tRNA(Ile2))-cytidine(34) + L-lysine + ATP = (tRNA(Ile2))-lysidine(34) + AMP + diphosphate + H2O.UniRule annotation

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
