3-(3-hydroxyphenyl)propanoate hydroxylase

3-(3-hydroxyphenyl)propanoate hydroxylase (, mhpA (gene)) is an enzyme with systematic name 3-(3-hydroxyphenyl)propanoate,NADH:oxygen oxidoreductase (2-hydroxylating). This enzyme catalyses the following chemical reaction


 * (1) 3-(3-hydroxyphenyl)propanoate + NADH + H+ + O2 $$\rightleftharpoons$$ 3-(2,3-dihydroxyphenyl)propanoate + H2O + NAD+
 * (2) (2E)-3-(3-hydroxyphenyl)prop-2-enoate + NADH + H+ + O2 $$\rightleftharpoons$$ (2E)-3-(2,3-dihydroxyphenyl)prop-2-enoate + H2O + NAD+

3-(3-hydroxyphenyl)propanoate hydroxylase is a flavoprotein (FAD).
