Tyrosine ammonia lyase (EC 4.3.1.23, L-tyrosine ammonia-lyase, TAL or Tyrase) is an enzyme in the natural phenols biosynthesis pathway. It transforms L-tyrosine into p-coumaric acid.[1][2][3]

L-Tyrosine  [math]\displaystyle{ \xrightarrow{TAL} }[/math] 130px|para-coumaric acid + Ammonia + H+

L-tyrosine = trans-p-hydroxycinnamate + NH3
