Sysname
L-tyrosine phenol-lyase (deaminating; pyruvate-forming)
Reaction(IUBMB)
L-tyrosine + H2O = phenol + pyruvate + NH3 [RN:R00728]
Reaction(KEGG)
Substrate
L-tyrosine [CPD:C00082];
H2O [CPD:C00001]
Product
phenol [CPD:C00146];
pyruvate [CPD:C00022];
NH3 [CPD:C00014]
Comment
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.
Pathway
Tyrosine metabolism
