Tyrosine ammonia-lyase

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.

 ${\displaystyle {\xrightarrow {TAL}}}$  + Ammonia + H⁺

L-tyrosine = trans-p-hydroxycinnamate + NH₃
