Viral fusion proteins are required for the fusion of viral and host membranes for all enveloped viruses. The structure of the Baculovirus postfusion form of glycoprotein gp64, a class III fusion protein, explains its ability to fuse with many different cell types, and structural comparisons suggest that all three classes of fusion proteins may be more closely related than previously thought.
