Reaction: L-tyrosine + H2O = phenol + pyruvate + NH3
Other name(s): β-tyrosinase; L-tyrosine phenol-lyase (deaminating)
Systematic name: L-tyrosine phenol-lyase (deaminating; pyruvate-forming)
Comments: A pyridoxal-phosphate protein. The enzyme also slowly catalyses pyruvate formation from D-tyrosine, S-methyl-L-cysteine, L-cysteine, L-serine and D-serine.
