Description:
<jats:title>Abstract</jats:title><jats:p>H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> can be accepted by several peroxygenases as a clean oxidant, able to supply both the necessary electrons and oxygen atom at the same time. The biocatalysts, in turn, are able to catalyse an array of interesting oxygen insertion reactions at enantio‐ and regio‐selectivities hard to attain with classical chemical methods. The sensitivity of most peroxygenases towards H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>, however, requires this oxidant to be generated <jats:italic>in situ</jats:italic>. Here, we suggest the application of (modified) sulfite oxidases to couple the oxidation of sulfites to the reduction of oxygen. This enables us to use calcium sulfite, an industrial waste product from scrubbing flue gases, as an electron donor to reduce oxygen. This will supply the required peroxide in a controlled manner and enables us to perform these challenging reactions at the expense of simple salts.</jats:p>
