  • Glucose isomerases with improved affinity for D-glucose
    Patent number: 5266475
    Abstract: A genetically engineered glucose isomerase with improved affinity for D-glucose and the method of preparation of such a glucose isomerase are disclosed. The glucose isomerase is obtained by mutagenizing the gene of a naturally occurring glucose isomerase such that a smaller amino acid replaces a larger amino acid in the catalytic site. In an especially advantageous embodiment of the present invention, the Clostridium glucose isomerase sequence is mutated and the residue replaced with a smaller amino acid is either Trp.sub.139 or Val.sub.186.
