The NIa protease of Potyviridae is the major viral protease that processes potyviral polyproteins. The NIa protease coding region of Cardamom mosaic virus (CdMV) is amplified from the viral cDNA, cloned and expressed in Escherichia coli. NIa protease forms inclusion bodies in E. Read More

Potato virus Y (PVY) is a common potyvirus of agricultural importance, belonging to the picornavirus superfamily of RNA plus-stranded viruses. A covalently linked virus-encoded protein VPg required for virus infectivity is situated at the 5' end of potyvirus RNA. VPg seems to be involved in multiple interactions, both with other viral products and host proteins. Read More

Cardamom mosaic virus, a possible member of the family Potyviridae has been associated with the mosaic disease (Katte disease) of small cardamom in India. A virus isolated from the symptomatic cardamom leaves was positive in ELISA only with antiserum to the Guatemalan isolate of cardamom mosaic virus and not with a number of other potyviruses. The size of the viral RNA (8. Read More

Positive sense ssRNA virus genomes from several genera have a viral protein genome-linked (VPg) attached over a phosphodiester bond to the 5' end of the genome. The VPgs of Southern bean mosaic virus (SBMV) and Ryegrass mottle virus (RGMoV) were purified from virions and analyzed by mass spectrometry. SBMV VPg was determined to be linked to RNA through a threonine residue at position one, whereas RGMoV VPg was linked to RNA through a serine also at the first position. Read More
