Glycoproteins virion assembly

The diminution in infectivity could be caused either by the production of virus particles having a lessened or abolished infectivity, or a decreased formation of infectious virions. The envelope glycoproteins of Semliki Forest virus and Sindbis virus synthesized in the presence of tunicamycin (and, thus, devoid of carbohydrate) are metabolically stable. They do not participate in the assembly of virus particles, although nucleocapsids are still formed under these conditions and are... [Pg.369]

Host cell transcription factors initiate transcription from the LTR, and new viral particles are formed at the plasma membrane. Gag-pol and gag precursors assemble together with two copies of viral RNA, and during the budding process env glycoproteins are incorporated into the viral membrane. In the newly formed virion, gag and gag-pol precursors are subjected to processing by the viral enzyme protease, which results in maturation of the virion. [For more details see (30).]... [Pg.419]
