title: [Modified model of potato virus X coat protein structure].
abstract: We propose the modified model of the structure of coat protein (CP) subunits in filamentous virions of potato virus X (PVX). The model is similar to the one proposed by us in 2001 for the CP of another helical plant virus (potato virus A) belonging to other (potyvirus) group. In this model the PVX CP molecule consist of two main domains--a bundle of four alpha-helices located close to the virion long axis and a so-called RNP-fold (or abCd-fold) located near the virion surface. Basing on this model we suggest possible mechanism of described by J.G. Atabekov and colleagues structural transition ("remodeling") of the PVX virions resulting from their interaction with virus-specific TGB-1 protein.
