Patent number: 11939605Abstract: Thermostable Cas9 nucleases. The present invention relates to the field of genetic engineering and more particularly to nucleic acid editing and genome modification. The present invention provides an isolated Cas protein or polypeptide fragment thereof having an amino acid sequence of SEQ ID NO: 1 or a sequence of at least 77% identity therewith. The Cas protein or polypeptide is capable of binding, cleaving, marking or modifying a double stranded target polynucleotide at a temperature in the range 20° C. and 100° C. inclusive. The invention further provides isolated nucleic acid molecules encoding the Cas9 nucleases, expression vectors and host cells. The invention also provides PAM sequences recognized by the Cas protein or polypeptide, The Cas9 nucleases disclosed herein provide novel tools for genetic engineering in general, in particular at elevated temperatures and are of particular value in the genetic manipulation of thermophilic organisms; particularly microorganisms.Type: GrantFiled: January 14, 2022Date of Patent: March 26, 2024Assignees: Wageningen Universiteit, Stichting Voor De Technische WetenschappenInventors: John Van Der Oost, Richard Van Kranenburg, Elleke Fenna Bosma, Ioannis Mougiakos, Prarthana Mohanraju

Publication number: 20190360002Abstract: A polynucleotide encoding a ThermoCas9 protein from Geobacillus thermodenitrificans and a constitutive promoter are used to engineer eukaryotic cells, e.g. fungi, yeast or algae, so that the ThermoCas9 endonuclease is integrated and expressed from the genome of the cell. Then, a second expression plasmid is used to transfect these ThermoCas9 expressing cells, the second plasmid containing an inducible promoter and a polynucleotide encoding a guide RNA. The guide RNA combines with the ThermoCas9 to provide the targeted endonuclease activity to cleave the cell DNA at a desired locus or gene of interest. A repair-oligo is also provided to the cell whereby following DNA cleavage, homologous recombination takes place in the cell with the repair-oligo so that either a deletion or substitution of nucleotides in the locus or gene of interest is achieved. Expression vectors and methods of using the vectors to achieve ThermoCas9 mediated gene editing are described whereby higher temperatures, e.g. greater than 30° C.Type: ApplicationFiled: December 14, 2017Publication date: November 28, 2019Inventors: John Van Der Oost, Richard Van Kranenburg, Elleke Fenna Bosma, Ioannis Mougiakos, Prarthana Mohanraju
