The enzyme tyrosine phenol-lyase (EC 4.1.99.2) catalyzes the chemical reaction. L-tyrosine + H 2 O phenol + pyruvate + NH 3. This enzyme belongs to the family of lyases, specifically in the "catch-all" class of carbon-carbon lyases.
Tyrosine ammonia lyase (TAL) is an enzyme in the natural phenols biosynthesis pathway. It transforms L-tyrosine into p-coumaric acid. Tyrosine is also the precursor to the pigment melanin. Tyrosine (or its precursor phenylalanine) is needed to synthesize the benzoquinone structure which forms part of coenzyme Q10. [23] [24]
This list contains a list of EC numbers for the fourth group, EC 4, lyases, placed in numerical order as determined by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology.

The enzyme phenylalanine ammonia lyase (EC 4.3.1.24) catalyzes the conversion of L-phenylalanine to ammonia and trans-cinnamic acid.: [1] L -phenylalanine = trans -cinnamate + NH 3 Phenylalanine ammonia lyase (PAL) is the first and committed step in the phenyl propanoid pathway and is therefore involved in the biosynthesis of the polyphenol ...
Phenylalanine ball and stick model spinning. Phenylalanine (symbol Phe or F) [3] is an essential α-amino acid with the formula C 9 H 11 NO 2.It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine.
