Abstract

The invention is in the field of enzymology. More in particular, it provides a method for the isomerization of glucose into fructose wherein the glucose is derived from lignocellulosic material. More in particular, the invention provides polypeptides encoding mutant glucose isomerase enzymes with improved glucose isomerase activity as compared to the corresponding wild type enzyme. The disclosed polypeptides are particularly suited for converting glucose to fructose in the presence of xylose.
