In enzymology, a phenylalanine decarboxylase (EC 4.1.1.53) is an enzyme that catalyzes the chemical reaction
- L-phenylalanine phenethylamine + CO2
Hence, this enzyme has one substrate, L-phenylalanine, and two products, phenethylamine and CO2.
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is L-phenylalanine carboxy-lyase (phenylethylamine-forming). Other names in common use include L-phenylalanine decarboxylase, aromatic L-amino acid decarboxylase, and L-phenylalanine carboxy-lyase. This enzyme participates in phenylalanine metabolism. It employs one cofactor, pyridoxal phosphate.
