NoV possesses a positive-sense, single-stranded RNA genome surrounded by an icosahedral capsid.
The three objectives of this research project are to: (i) identify the structural basis of subunitrecognition that guides assembly of large icosahedral capsids of type ranaviruses and elucidate the functionof the internal membrane in this process, (ii) determine the conformational changes that accompanymaturation of ranavirus capsids and regulate the headful packaging of the dsDNA genome, and (iii) ascertainthe mechanisms of cell entry by the naked capsids and enveloped ranavirus virions.
FeHV-1 consists of double-stranded DNA of 134 kilobases (Kb) with icosahedral capsids surrounded by a lipid envelope, presence of tegument between envelope and the capsid, and the diameter of virions range from 120 to 300nm (POVEY, 1979; GASKELL et al.
