Enzyme Information
4.1.99.2 |
Tyrosine phenol-lyase.
based on mapping to UniProt P31013
L-tyrosine + H(2)O = phenol + pyruvate + NH(3).
-!- The enzyme cleaves a carbon-carbon bond, releasing phenol and an unstable enamine product that tautomerizes to an imine form, which undergoes a hydrolytic deamination to form pyruvate and ammonia. -!- The latter reaction, which can occur spontaneously, can also be catalyzed by EC 3.5.99.10. -!- The enzyme also slowly catalyzes similar reactions with D-tyrosine, S-methyl-L-cysteine, L-cysteine, L-serine and D-serine.
