Enzyme Information
| 4.3.1.23 |
Tyrosine ammonia-lyase.
based on mapping to UniProt Q3IWB0
L-tyrosine = trans-p-hydroxycinnamate + ammonia.
-!- Member of the aromatic amino acid lyase family, other members of which are EC 4.3.1.3, EC 4.3.1.24 and EC 4.3.1.25. -!- Far more active with tyrosine than with phenylalanine as substrate, but the substrate specificity can be switched by mutation of a single amino acid (H89F) in the enzyme from the bacterium Rhodobacter sphaeroides. -!- Formerly EC 4.3.1.5.
