Role of N-linked glycosylation of the Hendra virus fusion protein.
The Hendra virus fusion (F) protein contains five potential sites for N-linked glycosylation in the ectodomain. Examination of F protein mutants with single asparagine-to-alanine mutations indicated that two sites in the F(2) subunit (N67 and N99) and two sites in the F(1) subunit (N414 and N464) normally undergo N-linked glycosylation. While N-linked modification at N414 is critical for protein folding and transport, F proteins lacking carbohydrates at N67, N99, or N464 remained fusogenically active. As N464 lies within heptad repeat B, these results contrast with those seen for several paramyxovirus F proteins.
