You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMed Many nonenveloped virus particles are stabilized by calcium ions bound in the interfaces between the protein subunits. These ions may have a role in the disassembly process. The small RNA phages of the Leviviridae family have T=3 quasi-symmetry and are unique among simple viruses in that they have a coat protein with a translational repressor activity and a fold that has not been observed in other viruses. The crystal structure of phage PRR1 has been determined to 3.5 A resolution. The structure shows a tentative binding site for a calcium ion close to the quasi-3-fold axis. The RNA-binding surface used for repressor activity is mostly conserved. The structure does not show any significant differences between quasi-equivalent subunits, which suggests that the assembly is not controlled by conformational switches as in many other simple viruses. The capsid of the small RNA phage PRR1 is stabilized by metal ions.,Persson M, Tars K, Liljas L J Mol Biol. 2008 Nov 21;383(4):914-22. Epub 2008 Aug 29.
