A structural model of pestivirus E(rns) based on disulfide bond connectivity and homology modeling reveals an extremely rare vicinal disulfide

, 2002
Erns is a pestivirus envelope glycoprotein and is the only known viral surface protein with RNase activity. Erns is a disulfide-linked homodimer of 100 kDa; it is found on the surface of pestivirus-infected cells and is secreted into the medium.
