Herpes simplex virus glycoprotein D bound to the human receptor HveA.
Mol.Cell, 8:169-179, 2001

PubMed Abstract: 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.
