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]
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.
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 ...
The crystal structure of the complex between YARS from Methanococcus jannaschii, tRNA(Tyr) and L-tyrosine has been solved at 1.95 Å resolution. [13] The crystal structures of the YARSs from Archeoglobus fulgidus , Pyrococcus horikoshii and Aeropyrum pernix have also been solved at high resolution. [ 14 ] (

The phenylpropanoids are a diverse family of organic compounds that are biosynthesized by plants from the amino acids phenylalanine and tyrosine in the shikimic acid pathway. [1] Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid , which is the central intermediate in ...
