Cloning and expression of DNA encoding a ripening from a polypeptide having sulfhydryl oxidase activity.

The invention relates to recombinant DNA technology for the production of an enzyme having sulfhydryl oxidase ("SOX") activity. This SOX-enzyme can be used where the oxidation of free sulfhydryl groups (thio compounds) to the corresponding disulfides is desirable. SOX enzyme may be used for treatment of bakery products or for removal of off-flavour from milk or beer
