NOVEL ENDOGLUCANASES

摘要

An enzyme preparation consisting essentially of an enzyme having cellulolytic activity and comprising a first amino acid sequence of 14 residues having the sequence Thr Arg X3 X4 Asp Cys Cys X8 X9 X10 Cys X12 Trp X14, in which X3 and X4 independently is Trp, Tyr or Phe; X8 is Arg, Lys or His; each of X9, X10, X12 and X13 is any of the 20 naturally occurring amino acid residues; and a second amino acid sequence of 5 residues having the sequence Trp Cys Cys XX4 Cys, in which XX4 is any of the 20 naturally occurring amino acid residues with the proviso that, in the first amino acid sequence, (i) when X12 is Ser, then X14 is not Ser, and (ii) when X12 is Gly, then X14 is not Ala; performs excellently in detergent, laundering, textile and papermaking pulp applications.
