Phenylalanine/tyrosine ammonia-lyase (EC 4.3.1.25, PTAL, bifunctional PAL) is an enzyme with systematic name L-phenylalanine(orL-tyrosine):trans-cinnamate(ortrans-p-hydroxycinnamate) ammonia-lyase.[1][2][3][4][5] This enzyme catalyses the following chemical reaction

(1) L-phenylalanine trans-cinnamate + NH3
(2) L- tyrosine trans-p-hydroxycinnamate + NH3

This enzyme is a member of the aromatic amino acid lyase family.
