GLYCOSYLATED PROTEIN EXPRESSION IN PROKARYOTES |
摘要 |
The present invention relates to a prokaryotic host cell comprising eukaryotic glycosyltransferase activity, where the eukaryotic glycosyltransferase activity is eukaryotic dolichyl-linked UDP-GlcNAc transferase activity and eukaryotic mannosyl-transferase activity. Also disclosed is a method of producing a glycosylated protein by providing a prokaryotic host cell comprising the eukaryotic glycosyltransferase activity and culturing the prokaryotic host cell under conditions effective to produce a glycosylated protein. Another aspect of the present invention pertains to a method for screening bacteria or bacteriophages by expressing one or more glycans on the surface of a bacteria, attaching a label on the one or more glycans on the surface of the bacteria or on the surface of a bacteriophage derived from the bacteria, and analyzing the label in a high-throughput format. A glycosylated antibody comprising an Fv portion which recognizes and binds to a native antigen and an Fc portion which is glycosylated at a conserved asparagine residue is also disclosed.
