Patent number: 11931405Abstract: A bioconjugate of an E. coli glucosylated O4 antigen polysaccharide covalently linked to a carrier protein and compositions thereof are provided. Also provided are recombinant host cells for producing the bioconjugate, and methods of producing the bioconjugate using the recombinant host cells. The recombinant host cells contain a nucleic acid encoding a glucosyl transferase capable of modifying the E. coli O4 antigen with glucose branching to produce the glucosylated O4 antigen polysaccharide. Bioconjugates of an E. coli glucosylated O4 antigen polysaccharide described herein can be used alone or in combination with one or more additional E. coli O-antigen polysaccharides to induce antibodies against an E. coli glucosylated antigen, and to vaccinate a subject against extra-intestinal pathogenic E. coli (ExPEC).Type: GrantFiled: July 28, 2022Date of Patent: March 19, 2024Assignees: GlaxoSmithKline Biologicals S.A.Inventors: Jeroen Geurtsen, Jan Theunis Poolman, Kellen Cristhina Fae, Pieter Jan Burghout, Eveline Marleen Weerdenburg, Patricia Ibarra Yon, Darren Robert Abbanat, Stefan Jochen Kemmler, Michael Thomas Kowarik, Manuela Mally, Veronica Gambillara Fonck, Martin Edward Braun, Maria Paula Carranza Sandmeier

Publication number: 20230190926Abstract: Methods of producing bioconjugates of O-antigen polysaccharides covalently linked to a carrier protein using recombinant host cells are provided. The recombinant host cells used in the methods described herein encode a particular oligosaccharyl transferase enzyme depending on the O-antigen polysaccharide bioconjugate to be produced. The oligosaccharyl transferase enzymes can be PglB oligosaccharyl transferase or variants thereof. Also provided are compositions containing the bioconjugates, and methods of using the bioconjugates and compositions described herein to vaccinate a subject against extra-intestinal pathogenic E. coli. (ExPEC).Type: ApplicationFiled: October 6, 2022Publication date: June 22, 2023Inventors: Jeroen GEURTSEN, Pieter Jan BURGHOUT, Eveline Marleen WEERDENBURG, Jan Theunis POOLMAN, Kellen Cristhina FAE, Patricia IBARRA YON, Darren Robert ABBANAT, Stefan Jochen KEMMLER, Michael Thomas KOWARIK, Manuela MALLY, Veronica GAMBILLARA FONCK, Martin Edward BRAUN, Maria Paula CARRANZA SANDMEIER
