The enzyme tyrosine phenol-lyase (EC 4.1.99.2) catalyzes the chemical reaction
- L-tyrosine + H2O phenol + pyruvate + NH3
This enzyme belongs to the family of lyases, specifically in the "catch-all" class of carbon-carbon lyases. The systematic name of this enzyme class is L-tyrosine phenol-lyase (deaminating; pyruvate-forming). Other names in common use include beta-tyrosinase, and L-tyrosine phenol-lyase (deaminating). This enzyme participates in tyrosine metabolism and nitrogen metabolism. It employs one cofactor, pyridoxal phosphate.
Structural studies
[edit]As of late 2007, five structures have been solved for this class of enzyme, with PDB accession codes 1C7G, 1TPL, 2EZ1, 2EZ2, and 2TPL.
