  • Cloning and expression of the exo-polygalacturonase gene from aspergillus
    Patent number: 5830737
    Abstract: The exo-polygalacturonase gene from Aspergillus is identified, and the enzyme encoded thereby is expressed. Specifically, the exo-polygalacturonase gene from Aspergillus tubingensis is is cloned and expressed, and DNA sequences from other Aspergillus strains that specifically hybridize therewith are identified. Novel expression vectors that comprise an exo-polygalacturonase encoding sequence, and host cells transformed therewith, are also provided. The invention further relates to the production of recombinant exo-polygalacturonase, and to the use of this protein.
