Structure of a C-terminally truncated form of glycoprotein D from HSV-1
|
OverviewOverview
Herpes simplex virus (HSV) infection requires binding of the viral, envelope glycoprotein D (gD) to cell surface receptors. We report the, X-ray structures of a soluble, truncated ectodomain of gD both alone and, in complex with the ectodomain of its cellular receptor HveA. Two bound, anions suggest possible binding sites for another gD receptor, a, 3-O-sulfonated heparan sulfate. Unexpectedly, the structures reveal a, V-like immunoglobulin (Ig) fold at the core of gD that is closely related, to cellular adhesion molecules and flanked by large N- and C-terminal, extensions. The receptor binding segment of gD, an N-terminal hairpin, appears conformationally flexible, suggesting that a conformational change, accompanying binding might be part of the viral entry mechanism.
