| Outline of Final Research Achievements |
We challenged the glycosylation of outer membrane vesicles (OMVs) produced by Escherichia coli cells for the targeting of human cells. The fusion protein of carbohydrate binding module (CBM) from other bacteria and outer membrane protein W (OmpW) from E. coli was designed for the glycosylation of OMVs. The successful expression of fusion protein on the E. coli OMVs was confirmed by the western blotting. However, examination of glycosylation using fluorescently-labeled carboxymethylcellulose revealed that the absorption of polysaccharide polymer on the OMVs was not promoted by the expression of fusion protein. It was thought to be due to the malfunction of fusion protein on the OMVs.
