| HC-Pro + H2O | tobacco vein mottling virus | the helper component proteinase HC-Pro is a multifunctional protein with three domains: the N-terminal third contributes to viral replication and aphid transmission, the central domain is required for viral vascular transport, and the C-terminal third contains the proteolytic domain. Proteolytic procession occurs at a Gly-Gly bond at its C-terminus. A Tyr-Xaa-Val-Gly-Gly sequence surrounding the cleavage site is highly conserved. The residues Cys649 and His722 within the proteolytic domain are essential for proteolysis | ? | - |
