Alphaviruses encode four nonstructural proteins (nsP1-4), initially produced as a polyprotein P1234. nsP4 is the core RNA-dependent RNA polymerase but all four nsPs are required for RNA synthesis. The early replication complex (RC) formed by the polyprotein P123 and nsP4 synthesizes minus ...
4 nsP1–detergent interactions. Micelle arrangement and membrane-binding regions of the double-ring structure. a, Lateral section of the double-ring map represented by a green mesh. A section of the map including one detergent micelle is highlighted in blue (left). The central panel shows two...
41. The infectious recombinant alphavirus particle of claim 30, in which the alphavirus base sequence having translation enhancing activity provides at least a 4-fold increase in translation activity. 42. A method for producing a substance having biological activity comprising: infecting a cell in...
Alphavirus nonstructural proteins are translated as a polyprotein that is ultimately cleaved into four mature proteins called nsP1, nsP2, nsP3, and nsP4 from their order in the polyprotein. The role of this nonstructural polyprotein, of cleavage intermediates, and of mature proteins in synthesis...

We show that nsP3 assembles into tubular structures made by a helical arrangement of its alphavirus unique domain (AUD). The nsP3 helical scaffolds are consistent with crown structures found on tomographic reconstructions of the mature viral RCs. In addition, nsP3 helices ...
