  • CELLULOSE-DEGRADING ENZYME COMPOSITION COMPRISING GH16
    Publication number: 20150329841
    Abstract: The present invention relates to a cellulose-degrading enzyme composition comprising one or more cellobiohydrolase and/or endoglucanase enzyme, and an effective amount of an isolated GH16 polypeptide, where the presence of the isolated GH16 polypeptide in the enzyme composition increases the rate or extent of degradation of a cellulosic substrate compared to an equivalent dosage of a corresponding cellulose-degrading enzyme composition lacking the at least one isolated GH16 polypeptide. The present invention also relates to a method for producing fermentable sugars from a cellulosic substrate using the above cellulose-degrading enzyme composition and to genetically modified microbes for produced the above cellulose-degrading enzyme composition.

  • Modified family 5 cellulases and uses thereof
    Patent number: 8609388
    Abstract: The present invention relates to a modified Family 5 cellulase comprising a substitution of an amino acid at position 363 with a non-native alanine, serine or threonine, the position determined from alignment of the modified Family 5 cellulase with amino acids 71-397 of a Trichoderma reesei Cel5A amino acid sequence as set forth in SEQ ID NO:1 and enzyme mixtures comprising same. Additionally provided is a genetic construct comprising a nucleic acid sequence encoding the modified Family 5 cellulase and a genetically modified microbe comprising the genetic construct. The invention also provides a process for producing the modified Family 5 cellulase.
    Type: Grant

  • MODIFIED FAMILY 5 CELLULASES AND USES THEREOF
    Publication number: 20130095554
    Abstract: The present invention relates to a modified Family 5 cellulase comprising a substitution of an amino acid at position 363 with a non-native alanine, serine or threonine, said position determined from alignment of the modified Family 5 cellulase with amino acids 71-397 of a Trichoderma reesei Cel5A amino acid sequence as set forth in SEQ ID NO:1 and enzyme mixtures comprising same. Additionally provided is a genetic construct comprising a nucleic acid sequence encoding the modified Family 5 cellulase and a genetically modified microbe comprising the genetic construct. The invention also provides a process for producing the modified Family 5 cellulase.
