| Abstract: | Glycoprotein B (gB) specified by herpes simplex virus can be extracted from virions or infected cells in the form of detergent-stable, heat-dissociable oligomers. The composition of the oligomers and requirements for their formation were investigated. Evidence is presented that the faster-migrating forms of the oligomers are homodimers of gB. Dimerization was shown to occur within minutes of polypeptide synthesis and did not depend on glycosylation, the expression of other viral proteins, or virion morphogenesis. The multiple, electrophoretically distinct forms of gB dimers differ in extent or rate of N-linked oligosaccharide processing and also have other differences that influence electrophoretic mobility. |
