ID 1.14.13.84 DE 4-hydroxyacetophenone monooxygenase. AN HAPMO. CA (4-hydroxyphenyl)ethan-1-one + NADPH + O(2) = 4-hydroxyphenyl acetate + CA NADP(+) + H(2)O. CF FAD. 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; //
