Gene expression by a hypovirulence-associated virus of the chestnut blight fungus involves two papain-like protease activities. Essential residues and cleavage site requirements for p48 autoproteolysis.

Abstract excerpt

Proteolytic processing plays a fundamental role in gene expression of a recently characterized viral-like double-stranded RNA associated with biological control of the chestnut blight fungus. Polypeptide p29, a papain-like protease, was shown to autocatalytically release itself from the NH2 terminus of the polyprotein specified by the first of two encoded open reading frames, ORF A (Choi, G. H., Shapira, R., and...
