  • Patent number: 11377645
    Abstract: Provided are Cas9 enzymes that have mutations that enhance their properties, relative to un-mutated Cas9. The altered Cas9 enzymes exhibit i) an increased rate of spacer acquisition, or ii) increased cleavage efficiency of targets with NAG PAMs, or a combination of i) and ii). The altered Cas9 enzymes comprise an amino acid substitution of 1473 and K500 in a Streptococcus pyogenes or similar Cas9 enzyme. Also provided are polynucleotides, including expression vectors that encode the Cas9 enzymes, cells that contain the polynucleotides, and methods of making and using such cells. The disclosure includes tagging, or labelling bacteria, and for enhancing phage acquired immunity in bacteria, such as those used in industrial processes, including the food and beverage industry, such as the dairy industry. The food products are also included.

  • Patent number: 11299732
    Abstract: Provided are compositions and methods for cleaving a DNA sequence in a cell. The methods involve comprising introducing into a cell a recombinant vector containing a clustered regularly interspaced short palindromic repeats (CRISPR) system. The system includes a CRISPR RNA (crRNA) targeted to a DNA sequence in the cell that is operatively linked to a promoter; and CRISPR-associated enzymes (Cas) 10, Cas6, and at least one Csm protein. The Cas 10 cleaves the DNA sequence only during transcription of the DNA sequence that is operatively linked to the promoter. Also provided are recombinant vectors for modifying cells, cells that contain the recombinant vectors and modifications introduced by them, and kits that include the modified vectors.

  • Publication number: 20200140847
    Abstract: Provided are compositions, methods, and kits for improving CRISPR-based editing of DNA targets by a CRISPR-associated (Cas) enzyme. The improvement is made by combining the Cas enzyme and a CRISPR targeting RNA a heterologous DNA repair enzyme that is at least one of RecBCD, AddAB, or AdnAB. The heterologous DNA repair enzyme may have inactivated nuclease activity. The method can include using a DNA repair template to introduce one or more changes into the edited DNA.
