Tryptophan—phenylpyruvate transaminase
In enzymology, a tryptophan-phenylpyruvate transaminase () is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are L-tryptophan and phenylpyruvate, whereas its two products are (indol-3-yl)pyruvate and L-phenylalanine. This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is L-tryptophan:phenylpyruvate aminotransferase. This enzyme is also called L-tryptophan-alpha-ketoisocaproate aminotransferase.
