Alphavirus nsP3 functions to form replication complexes transcribing negative-strand RNA

Abstract excerpt

The alphavirus mutant Sindbis virus HR ts4, which has been assigned to the A complementation group, possessed a selective defect in negative-strand synthesis that was similar although not identical to that observed for the B complementation group mutant ts11 (Y.-F. Wang, S. G. Sawicki, and D. L. Sawicki, J. Virol. 65:985-988, 1991). The causal mutation was identified as a change of a C to a U residue at...
