Assembly of viral membranes: maturation of the vesicular stomatitis virus glycoprotein in the presence of tunicamycin. 1978

T G Morrison, and C O McQuain, and D Simpson

The role of glycosylation in the maturation of the vesicular stomatitis virus (VSV) glycoprotein was studied by use of the antibiotic tunicamycin. Tunicamycin-treated VSV-infected cells synthesize an unglycosylated form of the VSV glycoprotein (R. Leavitt, S. Schlesinger, and S. Kornfeld, J. Virol. 21:375--385, 1977). We have found that tunicamycin has no effect on the attachment of the glycoprotein to intracellular membranes or on the transport of protein to the lumen of the endoplasmic reticulum. However, tunicamycin prevented the migration of the glycoprotein from the rough endoplasmic reticulum to smooth intracellular membranes.

D014415	Tunicamycin	An N-acetylglycosamine containing antiviral antibiotic obtained from Streptomyces lysosuperificus. It is also active against some bacteria and fungi, because it inhibits the glucosylation of proteins. Tunicamycin is used as tool in the study of microbial biosynthetic mechanisms.
D014721	Vesicular stomatitis Indiana virus	The type species of VESICULOVIRUS causing a disease symptomatically similar to FOOT-AND-MOUTH DISEASE in cattle, horses, and pigs. It may be transmitted to other species including humans, where it causes influenza-like symptoms.	Vesicular stomatitis-Indiana virus
