Protease required for processing picornaviral coat protein resides in the viral replicase gene

J Virol. 1979 Dec;32(3):770-8. doi: 10.1128/JVI.32.3.770-778.1979.

Abstract

Partial purification of the encephalomyocarditis protease synthesized in extracts from rabbit reticulocytes shows that the activity responsible for cleaving coat precursor protein cosediments with a previously unmapped virus-coded protein with an apparent molecular weight of 20,000. Tryptic analysis shows that this protein is derived from protein D, a virus-coded component of the encephalomyocarditis RNA polymerase.
