... different from those of other simple icosahedralviruses [13]. The main chain of the protein subunit foldsinto a five stranded antiparallel b-sheet (strands bC–bG)facing the interior of the phage particle, ... elution of the proteins can be explained by non-specific binding of the denatured coat proteins to the gel [34,35]. The elution of some D11N as capsids after urea treatment is probably the result of ... promote significant binding of bis-ANS to any of the particles, with the exception of T45S, which bound asmall amount of bis-ANS, increasing, by twofold, the emission of the probe (Fig. 7B)....
