Glycoprotein B (485-492), (C41H67N11O13), a peptide with the sequence H2N-Ser-Ser-Ile-Glu-Phe-Ala-Arg-Leu-OH, MW= 922.04. glycoprotein B is a viral glycoprotein that is involved in the viral cell entry of Herpes simplex virus (HSV). Herpesviruses have an envelope and an outer lipid bilayer which contains twelve surface glycoproteins. For infectivity to be attained, the double stranded DNA genome of HSV must enter the host cell through means of fusion of its envelope with the cellular membrane or via endocytosis(1). The herpesvirus glycoprotein B is the most highly conserved of all surface glycoproteins and acts primarily as a fusion protein. The precise functions of gB and gH/gL are unknown but they are required for viral entry into the cell and constitute the core fusion machinery. The claim that gB is involved in fusion comes from the notable syncytial phenotype caused by certain mutations within the cytoplasmic domain of glycoprotein B(2), as well as its strucutral homology to other viral fusion proteins(3).
