Expression of potyviral polyproteins in transgenic plants reveals three proteolytic activities required for complete processing.

The EMBO journal - 1 May 1990

Carrington J C, Freed D D, Oh C S

Abstract excerpt

All proteins encoded by the plant potyvirus, tobacco etch virus (TEV), arise by proteolytic processing of a single polyprotein. Two virus-encoded proteinases (NIa and HC-Pro) that catalyze most of the proteolytic events have been characterized previously. The two proteins that are derived from the N-terminal 87 kd region of the viral polyprotein are a 35 kd protein and HC-Pro (52 kd). It is demonstrated in this...
