发明名称 GH61 glycoside hydrolase protein variants and cofactors that enhance GH61 activity
摘要 The present invention provides various GH61 protein variants comprising various amino acid substitutions. The GH61 protein variants have an improved ability to synergize with cellulase enzymes, thereby increasing the yield of fermentable sugars obtained by saccharification of biomass. In some embodiments, sugars obtained from saccharification are fermented to produce numerous end-products, including but not limited to alcohol.
