  • Procaryotic xylose isomerase muteins
    Patent number: 5041378
    Abstract: Xylose isomerase (XI) muteins useful in the conversion of glucose to fructose or xylose to xylulose are obtained in usable amounts by protein structural and recombinant DNA methods, including x-ray crystallography, cloning, computer graphic modeling and site-directed mutagenesis and expression of the bacterial DNA sequences encoding native procaryotic xylose isomerase. These native sequences are altered to encode the xylose isomerase muteins having improved catalytic function and/or thermostability.
