A method for preparing an engineered glycoprotein using the mutant of EndoS2 includes coupling an activated oligosaccharide to a glycoprotein acceptor. The activated oligosaccharide is a glycan oxazoline.Type: ApplicationFiled: June 18, 2018Publication date: October 18, 2018Applicants: Academia SinicaInventors: Nan-Horng Lin, Lin-Ya Huang, Sachin S.

Publication number: 20180298363Abstract: The invention relates to a host cell comprising at least four different heterologous polynucleotides chose from the group of polynucleotides encoding cellulases, hemicellulases and pectinases, wherein the host cell is capable of producing the at least four different enzymes chosen from the group of cellulases, hemicellulases and pectinases, wherein the host cell is a filam-tous fungus and is capable of secretion of the at least four different enzymes. This host cell can suitably be used for the production of an enzyme composition that can be use in a process for the saccharification of cellulosic material.Type: ApplicationFiled: June 22, 2018Publication date: October 18, 2018Inventors: Alrik Pieter Los, Cornelis Maria Jacobus Sagt, Margot Elisabeth Francoise Schooneveld-Bergmans, Robbertus Antonius Damveld
