  • Patent number: 6812018
    Abstract: Disclosed are variant thermostable cellulases, nucleic acids encoding the variants and methods for producing the variants. The variant thermostable cellulases have the amino acid sequence of a glycosyl hydrolase of family 12 wherein one or more amino acid residues which are not part of the catalytic domain are deleted. In specific embodiments, the variant thermostable cellulase is a variant of Cel12A of Rhodothermus marinus.

  • Publication number: 20040209249
    Abstract: The present invention provides a method that can facilitate structure determination of target proteins by x-ray crystallography. It is a method of rational crystallization of members of a target protein family obtained through specific amplification of corresponding genes from natural diversity. The method makes broad biodiversity accessible through sampling and ecological enrichment of diverse high-temperature ecosystems containing thermophilic microorganisms including uncultivable and previously unknown organisms. The method provides means to circumvent many potential problems and bottlenecks in crystal structure determination by selection of suitable proteins directly from nature. The invention combines methods of accessing and screening vast natural diversity and the inherent suitability of thermostable proteins for crystallization in order to maximize probability of successful structure determination.
