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