Function

[APO1_AGRAE] Aromatic peroxidase that oxidizes aryl alcohols into the corresponding aldehydes and then into the corresponding benzoic acids. Oxidizes toluene and naphthalene. Catalyzes the regioselective peroxide-dependent hydroxylation of propranolol and diclofenac to 5-hydroxypropranolol and 4'-hydroxydiclofenac. Catalyzes the regioselective peroxide-dependent hydroxylation of naphthalene to 1-naphthol or 2-naphthol via a naphthalene 1,2-oxide intermediate. Catalyzes the regioselective peroxide-dependent oxidation of pyridine to pyridine N-oxide. Halogenates monochlorodimedone and phenol. Oxidizes the sulfer-containing heterocycle dibenzothiophene to yield ring-hydroxylation products and to a lesser extent sulfoxidation products.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]

Publication Abstract from PubMed

Aromatic peroxygenases (APOs) represent a unique oxidoreductase sub-subclass of heme proteins with peroxygenase and peroxidase activity and were thus recently assigned a distinct EC classification (EC 1.11.2.1). They catalyze, inter alia, oxyfunctionalization reactions of aromatic and aliphatic hydrocarbons with remarkable regio and stereoselectivities. Compared with cytochrome P450, APOs appear to be the choice enzymes for oxyfunctionalizations in organic synthesis due to their independence from a cellular environment and their greater chemical versatility. Here, the first two crystal structures of a heavily glycosylated fungal aromatic peroxygenase (AaeAPO) are described. They reveal different pH-dependent ligand-binding modes. We model the fitting of various substrates in AaeAPO, illustrating the way the enzyme oxygenates polycyclic aromatic hydrocarbons (PAHs). Spatial restrictions by a phenylalanine pentad in the active-site environment govern substrate specificity in AaeAPO.
