 4-hydroxymandelate synthase

In enzymology, a 4-hydroxymandelate synthase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are 4-hydroxyphenylpyruvate and oxygen, whereas its two products are 4-hydroxymandelate and carbon dioxide.This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O2 as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases).
