Accepted name: tryptophan—phenylpyruvate transaminase
Reaction: L-tryptophan + phenylpyruvate = (indol-3-yl)pyruvate + L-phenylalanine
Other name(s): L-tryptophan-α-ketoisocaproate aminotransferase
Systematic name: L-tryptophan:phenylpyruvate aminotransferase
Comments: Valine, leucine and isoleucine can replace tryptophan as amino donor.
