abstract = {Human noroviruses recognize histo blood group antigens
(HBGAs) as cellular attachment factors. Recently, it has
been discovered that norovirus infection can be
significantly enhanced by HBGA binding. Yet the attachment
process and how it promotes host-cell entry is only poorly
understood. The binding of a norovirus protruding (P) domain
of a predominant GII.4 Saga strain to HBGAs at atomic
resolution was studied. So far, independent and equivalent
multiple binding sites were held responsible for attachment.
Using NMR experiments we show that norovirus-HBGA binding is
a cooperative multi-step process, and native mass
spectrometry reveals four instead of two HBGA binding sites
per P-dimer. An accompanying crystallographic study has
disclosed four instead of two l-fucose binding sites per
P-dimer of a related GII.10 strain1 further supporting our
findings. We have uncovered a novel paradigm for
norovirus-HBGA recognition that will inspire further studies
into norovirus–host interactions.},
