X-ray structure of the arenavirus glycoprotein GP2 in its postfusion hairpin conformation.

Arenaviruses are important agents of zoonotic disease worldwide. The virions expose a tripartite envelope glycoprotein complex at their surface, formed by the glycoprotein subunits GP1, GP2 and the stable signal peptide. This complex is responsible for binding to target cells and for the subsequent fusion of viral and host-cell membranes for entry. During… CONTINUE READING
