WARS (gene)

Summary

Tryptophanyl-tRNA synthetase, cytoplasmic is an aminoacyl-tRNA synthetase enzyme that attaches the amino acid tryptophan to its cognate tRNA. In humans, it is encoded by the WARS gene.[5][6][7]

Two forms of tryptophanyl-tRNA synthetase exist, a cytoplasmic form, named WARS, and a mitochondrial form, named WARS2. Tryptophanyl-tRNA synthetase (WARS) catalyzes the aminoacylation of tRNA(trp) with tryptophan and is induced by interferon. Tryptophanyl-tRNA synthetase belongs to the class I tRNA synthetase family. Four transcript variants encoding two different isoforms have been found for this gene.[7]

Phenylalanine Incorporation edit

Although WARS1 classically aminoacylates tryptophan, during states tryptophan depeletion, this enzyme has been observed to activate both tryptophan and phenylalanine.[8]
