Expression, Purification, and Crystallization of Full-Length HSV-1 gB for Structure Determination

Abstract

HSV glycoproteins play important roles in the viral life cycle, particularly viral cell entry. Here we describe the protocol for expression, purification, and crystallization of full-length HSV-1 glycoprotein B. The protocol provides a framework for incorporating transmembrane domain-stabilizing amphipols into the crystallization setup and can be adapted to isolate other complete HSV glycoproteins.
