  • Patent number: 11685913
    Abstract: A number of T4 DNA ligase mutants exhibiting enhanced ligation activity in the presence of high salt concentrations compared to the wild-type ligase were engineered, characterized, and selected via gel electrophoresis of ligation products from a standard ligation assay. Ligase catalyzes the formation of phosphodiester bonds between the 5? and 3? ends of complementary cohesive ends or blunt ends of duplex DNA, a process that is vital to numerous molecular biology processes including cloning and sequencing.

  • Patent number: 11674128
    Abstract: The presently claimed invention offers programmable and precise regulation of Cas9 functions by utilizing a set of compact Cas9 derivatives created by deleting conserved HNH and/or REC-C domains based on the structural information across variant class 2 CRISPR effectors. In addition, a novel strategy for engineering the dimeric gRNA-guided nuclease by splitting the mini-dSaCas9 and fusing the FokI domain right after the split point is claimed to increase the on-target DNA cleavage efficiency and potentially reduce the off-target effect because of a closer proximity of dimeric Fold nuclease to the target sequence. By combining the optimized and compact gRNA expression cassette and the downsized SaCas9 derivatives, the entire CRISPR/Cas system with different effector domains for transactivation, DNA cleavage and base editing is loaded into a single AAV virus. Such an all-in-one AAV-CRISPR/Cas9 system will be particularly appealing in biomedical applications that require safe and efficient delivery in vivo.
