Résumé

Processing of the 112 kDa ('112K') protein encoded by cowpea mosaic virus RNA 1 was examined in cowpea mesophyll protoplasts using a transient expression system. Cleavage of the 112K protein occurred via two alternative pathways either into VPg and 110K (24K + 87K) or into 26K (VPg + 24K) and 87K proteins. The 26K protein can be further cleaved into VPg and 24K proteins. The results support a model in which the 112K protein functions as the precursor of VPg during initiation of replication.
