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.
application of microwave in organic synthesis, sparked by the pioneering papers of Gedye, Majetich and their co-workers in 1986: has demonstrated that reactions can be conducted safely in commercial microwave ovens with remarkable rate enhancements and dramatic reductions of reaction times compared to conventional heating.5 Bogdal et ul. reported a method of N-alkylations of carbazole undermicrowave irradiation
A substantially water-free, liquid, enzyme-containing composition comprises: (A) an enzyme; (B) a substance selected from (i) substances which in aqueous medium are substrates for said enzyme, (ii) substances which in aqueous medium are precursors for substrates for said enzyme, and (iii) substances which are cofactors for said enzyme; and (C) a non-aqueous liquid phase.
Novel laccases, nucleic acid sequences encoding such laccases, and vectors and host cells for expressing the laccases are described. The novel laccase enzymes may be employed in conjunction with mediators to provide an improved method for bleaching denim fabrics.
