  • Patent number: 11427829
    Abstract: Compositions and methods are provided for genome modification at a target site in the genome of a filamentous fungal cell. The methods and compositions are drawn to a guide polynucleotide/Cas endonuclease system for modifying or altering the target site. Aspects in which the filamentous fungal cell being modified has a defective non-homologous end joining pathway are also provided.

  • Publication number: 20220136027
    Abstract: The present invention related to a method for preparing a protein hydrolysate from a proteinaceous material by contacting the material with a proteolytic enzyme mixture having a proline specific exopeptidase. In particular, the proline specific exopeptidase is an aminopeptidase specific for at the five amino acid N-terminal sequence X-Pro-Gln-Glv-Pro-, where X is any amino acid. The present invention also relates to use of the aminopeptidase with a second exopeptidase and an endopeptidase.

  • Publication number: 20210315238
    Abstract: The present invention provides proline specific endopeptidases. The present invention further provides methods for use of proline specific endopeptidases for use in reduction of chill haze in a beverage, including beer. The present invention further provides methods for producing protein hydrolysates using proline specific endopeptidases. Also provided are methods of treating disease, including Celiac disease using proline specific endopeptidases. Also provided are nucleic acids encoding the proline specific endopeptidases and host cells for production of the proline specific endopeptidases.
