Tyrosine is one of the amino acid used in protein synthesis. The tyrosine biosynthesis pathways is connected with the chorismate biosynthesis pathway. Chorismate biosynthesis produce the chorismate, which can further be converted to prephenate by T-protein. Combined with cofactor, NAD, prephenate has been further converted to 4-Hydroxyphenylpyruvic acid by T-protein with generated NADH and carbon dioxide. Tyrosine aminotransferase catalyzes 4-Hydroxyphenylpyruvic acid to tyrosine, and also converts glutamic acid to oxoglutaric acid. Tyrosine will be further catalyzed into various molecules such as 2-iminoacetate, p-Cresol, 5'Deoxyadenosine and L-Methionine; or it will be exported from cell via the lysine exporter.
