The present invention relates to an enzymatic composition capable of killing or inhibiting microbial cells or micro-organisms, e.g. in laundry, on hard surfaces, in water systems, on skin, on teeth or on mucous membranes. The present invention also relates to the use of said enzymatic composition for preserving food products, cosmetics, paints, coatings, etc.
The present invention relates to variants of a parent laccase. The present invention also relates to polynucleotides encoding the variant laccases and to nucleic acid constructs, vectors, and host cells comprising the polynucleotides, and methods of using the variant enzymes.

enabled us to discover an enantioselective process in which the fragile conjugate‐addition product generated in the first stage is rapidly cyclized into the stable isoxazoline under acidic conditions, with conservation of enantiomeric excess. In summary, herein we describe synthetically useful protocols for accessing 3‐unsubstituted 2‐isoxazolines in both the enantioselective and racemic manner. The
