Truncation of the carboxy-terminal 28 amino acids of glycoprotein B specified by herpes simplex virus type 1 mutant amb1511-7 causes extensive cell fusion.
Three amber mutations were introduced proximal to the syn3 locus of the herpes simplex virus type 1 glycoprotein B (gB) gene specifying gB derivatives lacking the carboxy-terminal 28, 49, or 64 amino acids. A complementation system that utilized gBs expressed in COS cells to complement gB-null virus K delta T was established. The 49- or 64-amino-acid-truncated gBs failed to complement gB-null virus K delta T, while the 28-amino-acid-truncated gB complemented K delta T efficiently. Mutant herpes simplex virus type 1 KOS (amb1511-7) specifying the 28-amino-acid-truncated gB fused Vero cells extensively.
