WebbEffects of TMV replicase protein. As was previously mentioned, the TMV replicase complex, translated immediately after viral disassembly, is composed of two 5′ ORFs which encode 183 and 126 kDa proteins. The replicase complex is associated with virus replication and, in particular, the 126 kDa component has been identified as the TMV VSR.
