MUTATED CELLOBIOSE DEHYDROGENASE WITH MODIFIED SUBSTRATE SPECIFICITY

摘要

The present invention relates to a modified cellobiose dehydrogenase (CDH) or its functional flavodehydrogenase domain having a substitution at the amino acid corresponding to N721 of SEQ ID NO: 5 (CDH from M . thermophilum ) by glutamine, isoleucine, threonine or leucine or a substitution of the asparagine in the active canter motif having the amino acid sequence NHW by glutamine, isoleucine, threonine or leucine.
