Protein

Tryptophan--tRNA ligase 2

Gene

trpS2

Organism
Deinococcus radiodurans (strain ATCC 13939 / DSM 20539 / JCM 16871 / LMG 4051 / NBRC 15346 / NCIMB 9279 / R1 / VKM B-1422)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the formation of 5'adenyl-Trp and tRNA(Trp) but with 5-fold less activity than TrpRS. Increases the solubility of the nitric oxide synthase oxygenase (nos), as well as its affinity for substrate L-arginine and its nitric-oxide synthase activity. The complex between trpS2 and nos catalyzes the regioselective nitration of tryptophan at the 4-position.1 Publication

Catalytic activityi

ATP + L-tryptophan + tRNA(Trp) = AMP + diphosphate + L-tryptophyl-tRNA(Trp).

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
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.
