Function

APO1_CYCAE 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 sulfur-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

The hydroxylation of fatty acids is an appealing reaction in synthetic chemistry, although the lack of selective catalysts hampers its industrial implementation. In this study, we have engineered a highly regioselective fungal peroxygenase for the omega-1 hydroxylation of fatty acids with quenched stepwise over-oxidation. One single mutation near the Phe catalytic tripod narrowed the heme cavity, promoting a dramatic shift toward subterminal hydroxylation with a drop in the over-oxidation activity. While crystallographic soaking experiments and molecular dynamic simulations shed light on this unique oxidation pattern, the selective biocatalyst was produced by Pichia pastoris at 0.4 g L(-1) in a fed-batch bioreactor and used in the preparative synthesis of 1.4 g of (omega-1)-hydroxytetradecanoic acid with 95 % regioselectivity and 83 % ee for the S enantiomer.
