FR3 and high-rate-of-entry mutants. (A) Ribbon structure of the gB crown. Residues altered in fast-entry mutants are depicted as spheres. (B) All mutants were expressed at or near WT levels. (C and D) The kinetics of fusion were either WT (C) or enhanced over WT kinetics (D) and were maintained over a long period. (E) Both hyperfusogenic mutants exhibited a fast phenotype right from the initial stages of fusion.
