Phenylalanine/tyrosine ammonia-lyase (EC 4.3.1.25, PTAL, bifunctional PAL) is an enzyme with systematic name L-phenylalanine(or L-tyrosine):trans-cinnamate(or trans-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.
