IUBMB Enzyme Nomenclature


Accepted name: phenylacetone monooxygenase

Reaction: phenylacetone + NADPH + H+ + O2 = benzyl acetate + NADP+ + H2O

Other name(s): PAMO

Systematic name: phenylacetone,NADPH:oxygen oxidoreductase

Comments: A flavoprotein (FAD). NADH cannot replace NADPH as coenzyme. In addition to phenylacetone, which is the best substrate found to date, this Baeyer-Villiger monooxygenase can oxidize other aromatic ketones [1-(4-hydroxyphenyl)propan-2-one, 1-(4-hydroxyphenyl)propan-2-one and 3-phenylbutan-2-one], some alipatic ketones (e.g. dodecan-2-one) and sulfides (e.g. 1-methyl-4-(methylsulfanyl)benzene).
