摘要

Variant isolated from celobioidrolase polypeptide precursor, isolated, construction of nucleic acid, expression vector, host cell, method for producing a variant of celobioidrolase precursor, methods for obtaining the variant to degrade or convert a cellulosic material, to prod Uzir a fermentation product and fermenting a cellulosic material, and composition of the enzyme.The present invention relates to variants of celobioidrolase precursor. The present invention also relates to polynucleotides encoding encoding the variants of celobioidrolase; construction of nucleic acid vectors, and host cells comprising the polynucleotides encoding; and methods of using the celobioidrolase variants.
