additional information | in vitro, protein nsp9 of equine arteritis virus shows weak de novo polymerase activity on homopolymeric RNA templates. The RNA-synthesizing activities observed in de novo and primer-dependent polymerase and terminal transferase assays cannot be attributed to recombinant EAV nsp9-RdRp. The polymerase assay employing 32P-labeled NTPs is sensitive enough to detect the activity of trace amounts of contaminating T7 RNA polymerase. This polymerase is also able to act on templates lacking the established T7 promoter requirements | equine arteritis virus | ? | - |
