Protein Name: Tryptophan--tRNA ligase, cytoplasmic

UniprotKB/SwissProt ID: P32921 (P32921)

Gene Name: Wars1

Organism: Mus musculus (Mouse)

Function: Catalyzes the attachment of tryptophan to tRNA(Trp) in a two-step reaction: tryptophan is first activated by ATP to form Trp-AMP and then transferred to the acceptor end of the tRNA(Trp). Could also possess an angiostatic activity

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm
