Evidence that the potyvirus P1 proteinase functions in trans as an accessory factor for genome amplification.

Journal of virology - 1 Jun 1995

Abstract excerpt

The tobacco etch potyvirus (TEV) polyprotein is proteolytically processed by three viral proteinases (NIa, HC-Pro, and P1). While the NIa and HC-Pro proteinases each provide multiple functions essential for viral infectivity, the role of the P1 proteinase beyond its autoproteolytic activity is un...
