Abstract
The present invention relates to enzyme preparations consisting essentially of an enzyme which has cellulytic activity and comprises a first amino acid sequence consisting of 14 amino acid residues having the following sequence Thr Arg Xaa Xaa Asp Cys Cys Xaa Xaa (SEQ ID NO:79) 1 2 3 4 5 6 7 8 9 - Xaa Cys Xaa Trp Xaa 10 11 12 13 14 and a second amino acid sequence consisting of 5 amino acid residues having the following sequence Trp Cys Cys Xaa Cys (SEQ ID NO:80) 1 2 3 4 5 wherein, in position 3 of the first sequence, the amino acid is Trp, Tyr or Phe; in position 4 of the first sequence, the amino acid is Trp, Tyr or Phe; in position 8 of the first sequence, the amino acid is Arg, Lys or His; in position 9, 10, 12 and 14, respectively, of the first sequence, and in position 4 of the second sequence, the amino acid is any of the 20 naturally occurring amino acid residues with the provisos that, in the first amino acid sequence, (i) when the amino residue in position 12 is Ser, then the amino acid residue in position 14 is not Ser, and (ii) when the amino residue in position 12 is Gly, then the amino acid residue in position 14 is not Ala, performs very good in industrial applicatio…
