KEGG   ENZYME: 1.14.13.84
Entry
EC 1.14.13.84               Enzyme                                 

Name
4-hydroxyacetophenone monooxygenase;
HAPMO
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With NADH or NADPH as one donor, and incorporation of one atom of oxygen into the other donor
Sysname
(4-hydroxyphenyl)ethan-1-one,NADPH:oxygen oxidoreductase (ester-forming)
Reaction(IUBMB)
(4-hydroxyphenyl)ethan-1-one + NADPH + H+ + O2 = 4-hydroxyphenyl acetate + NADP+ + H2O [RN:R06892]
Reaction(KEGG)
R06892
Substrate
(4-hydroxyphenyl)ethan-1-one [CPD:C10700];
NADPH [CPD:C00005];
H+ [CPD:C00080];
O2 [CPD:C00007]
Product
4-hydroxyphenyl acetate [CPD:C13636];
NADP+ [CPD:C00006];
H2O [CPD:C00001]
Comment
Contains FAD. The enzyme from Pseudomonas fluorescens ACB catalyses the conversion of a wide range of acetophenone derivatives. Highest activity occurs with compounds bearing an electron-donating substituent at the para position of the aromatic ring [1]. In the absence of substrate, the enzyme can act as an NAD(P)H oxidase (EC 1.6.3.1).
