摘要： Chemoenzymatic process for coproducing a disulfide and a sulfoxide or a sulfone The present invention relates to a chemoenzymatic process for coproducing disulfide and sulfoxide or sulfone from a composition M comprising: 1) a sulfide, 2) optionally an oxidizing agent, 3) an organic compound bearing at least one thiol group, 4) an enzyme E catalyzing the oxidation of said sulfide to sulfoxide or to sulfone, 5) an enzyme D catalyzing the formation of a disulfide bridge between two equivalents of said organic compound bearing at least one thiol group to form a dimer, and 6) a cofactor common to the two enzymes E and D; and also to a composition enabling especially the implementation of this process. The present invention also relates to the use of a mercaptan for reducing a disulfide bridge formed between two equivalents of an organic compound bearing at least one thiol group, and more particularly to the use thereof as regeneration substrate of the process described above.
