Effect of herpes simplex virus type 1 on cellular pools of oligosaccharide-lipid.
Incorporation of [3H]mannose into cellular pools of mannosylphosphoryl dolichol (Man-P-Dol), oligosaccharide-lipid, and glycoprotein was measured and compared in herpes simplex virus type 1 (HSV-1)-infected cells and -uninfected cells. While mannose incorporation into the monosaccharide-dolichol fraction was similar in infected or uninfected Vero cells, incorporation into the oligosaccharide-lipid fraction was markedly reduced in HSV-1-infected cells (64% of control levels). In contrast, mannose incorporation into glycoprotein was significantly increased in virus-infected cells versus uninfected cells (194% of control levels). The kinetics of incorporation into the various fractions was examined and it was determined that there was minimal increase in mannose incorporation into oligosaccharide-lipid after 8 hr postinfection in virus-infected cells. This corresponded to the time at which nonglycosylated precursors of the HSV-1 glycoproteins were first detected in association with the nuclear fraction. These data suggest that there is an accelerated turnover of oligosaccharide-lipid in virus-infected Vero cells which is most likely due to extensive glycoprotein synthesis.
