Abstract excerpt
The celH gene from Clostridium thermocellum encodes a protein containing 900 residues and three components, including Cel5E, Lic26a, and carbohydrate-binding domains. Cel5E is a member of the glycoside hydrolase-5 family and is a bifunctional xylanase/cellulase enzyme. We targeted a semi-hydrophobic pocket near the Cel5E active site and theoretically screened mutated variants for enhanced levels of thermal...
