pubmed:abstractText |
Addition of 1 to 10 mM 2-deoxy-D-glucose (2-dg) or glucosamine (gln) to the growth medium of vaccinia virus-infected cells inhibited the release of extracellular enveloped vaccinia virus (EEV) without affecting the production of intracellular naked vaccinia virus (INV) particles. In contrast, INV infectivity (particles per PFU) was decreased sevenfold by 50 mM 2-dg. Treatment with 2-dg reduced but did not eliminate glycosylation of the INV 37,000-molecular-weight glycoprotein. The kinetics of sensitivity to inhibitor addition experiments and inhibitor reversal experiments indicated that EEV release was dependent on glycosylation before 8 h postinfection. This was supported by polyacrylamide gel electrophoretic analysis of the synthesis kinetics for cell membrane-associated vaccinia glycoproteins in 2-dg-inhibited infected cells. The dependence of vaccinia protein glycosylation before 8 h postinfection for efficient EEV release was observed in spite of the fact that the period of greatest glycoprotein synthesis was 8 to 12 h postinfection. The presence of 2-dg resulted in an incompletely glycosylated 89,000-molecular-weight glycoprotein, as indicated by a reduction in the apparent glycoprotein molecular weight. The morphological event affected by the inhibitors was the acquisition by INV of a double-membrane structure from the Golgi apparatus. This morphological intermediate is necessary for release of EEV.
