Accepted name: 3-(3-hydroxyphenyl)propanoate hydroxylase
Reaction: (1) 3-(3-hydroxyphenyl)propanoate + NADH + H+ + O2 = 3-(2,3-dihydroxyphenyl)propanoate + H2O + NAD+
(2) (2E)-3-(3-hydroxyphenyl)prop-2-enoate + NADH + H+ + O2 = (2E)-3-(2,3-dihydroxyphenyl)prop-2-enoate + H2O + NAD+
Glossary: 3-hydroxycinnamate = 3-coumarate = 3-(3-hydroxyphenyl)prop-2-enoate
Other name(s): mhpA (gene name)
Systematic name: 3-(3-hydroxyphenyl)propanoate,NADH:oxygen oxidoreductase (2-hydroxylating)
Comments: A flavoprotein (FAD). This enzyme participates in a meta-cleavage pathway employed by the bacterium Escherichia coli for the degradation of various phenylpropanoid compounds.
