Abstract
Recently, combined nuclear magnetic resonance (NMR), native mass spectrometry (MS) and X-ray crystallographic studies have demonstrated that binding of histo-blood group antigens (HBGAs) to norovirus capsid protein (P-dimers) is a cooperative process involving four binding pockets. Here, we show that binding to norovirus virus-like particles (VLPs) is even more complex. We performed saturation transfer difference (STD) NMR titration experiments with two representative genotypes of norovirus VLPs using L-fucose as a minimal HBGA. Compared to titrations with P-dimers, the corresponding binding isotherms reflect at least six distinct binding events.
