摘要
A modified model was proposed for the tertiary structure of the coat protein (CP) molecules in potato virus X (PVX) virions, similar to the original model of 2001 describing the structure of CP of potato virus A, a member of another group of filamentous viruses. According to the new model, CP comprises two main structural domains, namely, a bundle of α-helices, located near the long axis of the virion, and the socalled RNP fold (or abCd fold), located in the vicinity of its surface. The model made it possible to suggest a possible mechanism of the PVX virion structural rearrangement (remodeling) resulting from translational activation of virions by the TGB1 movement protein according to Atabekov and colleagues.
