| Research Abstract |
By using novel yeast-derived HBsAg L particles, named bio-nanocapsules (BNC), as noninfectious subviral particles, we studied the infectious mechanisms, especially the membrane fusion mechanism that remain unsolved, of HBV. We successfully identified a novel membrane fusion motif located at the N-terminal region of HBsAg L protein. We also demonstrated that the hydrophobic phenylalanine residues (Phe13 and Phe14) were essential for this fusion activity.
