Biology:Plant seed peroxygenase

Plant seed peroxygenase (EC 1.11.2.3, plant peroxygenase, soybean peroxygenase) is an enzyme with systematic name substrate:hydroperoxide oxidoreductase (RH-hydroxylating or epoxidising).^[1]^[2]^[3]^[4]^[5] This enzyme catalyses the following chemical reaction

R₁H + R₂OOH [math]\displaystyle{ \rightleftharpoons }[/math] R₁OH + R₂OH

This enzyme is a heme protein that contains calcium binding motif.
