ID 1.14.13.84 DE 4-hydroxyacetophenone monooxygenase. AN HAPMO. CA 4'-hydroxyacetophenone + H(+) + NADPH + O2 = 4-acetoxyphenol + H2O + CA NADP(+). CC -!- The enzyme from Pseudomonas fluorescens ACB catalyzes the conversion CC of a wide range of acetophenone derivatives. CC -!- Highest activity occurs with compounds bearing an electron-donating CC substituent at the para position of the aromatic ring. CC -!- In the absence of substrate, the enzyme can act as an NADPH oxidase CC (EC 1.6.3.1). DR Q93TJ5, HAPMO_PSEFL; //
