摘要:
A method for producing human-like glycoproteins by expressing a Class 2 α-mannosidase having a substrate specificity for Manα1,3 and Manα1,6 glycosidic linkages in a lower eukaryote is disclosed. Hydrolysis of these linkages on oligosaccharides produces substrates for further N-glycan processing in the secretory pathway.
摘要:
Described herein are methods and genetically engineered fungal cells useful for producing target molecules containing mammalian-like complex N-glycans or containing intermediates in a mammalian glycosyiation pathway.

A method for producing human-like glycoproteins by expressing a Class 2 null-mannosidase having a substrate specificity for Mannull1,3 and Mannull1,6 glycosidic linkages in a lower eukaryote is disclosed. Hydrolysis of these linkages on oligosaccharides produces substrates for further N-glycan processing in the secretory pathway.
摘要:
The present invention provides genetically engineered strains of methylotrophic yeast including Pichia and especially Pichia pastoris capable of producing proteins with reduced or modified glycosylation. Methods of producing glycoproteins with reduced and/or modified glycosylation using such genetically engineered strains of Pichia are also provided. Vectors, which comprise coding sequences for null-1,2-mannosidase I, glucosidase II, GlcNAc-tranferase I and mannosidase II or comprising OCH1 disrupting sequence, for transforming methylotrophic yeasts are contemplated by the present invention. Kit for providing the comtemplated vectors are also included in this invention.
摘要:
The present invention relates to the field of glycosylation engineering of proteins. More particularly, the present invention relates to nucleic acid molecules, including fusion constructs, having catalytic activity and the use of same in glycosylation engineering of host cells to generate polypeptides with improved therapeutic properties, including antibodies with increased Fc receptor binding and increased effector function.

摘要:
Method for providing a hypoallergenic glycoprotein includes growing at least one of a mutated plant, a part of the mutated plant, plant cells produced from the mutated plant, a transgenic plant, a part of the transgenic plant and plant cells produced from the transgenic plant wherein an activity of an enzyme Golgi α-mannosidase II has been eliminated or decreased so as to obtain a grown material. The hypoallergenic glycoprotein is isolated from the grown material.
