Spike and host glycan determinants of HKU1 airway tropism
It is shown that spikes from both serotypes of HKU1 preferentially bind 9-O-acetylated α2,8-linked disialosides, and molecular dynamics simulations indicated that membrane-embedded GT3, but not GD3, presents its glycan chain in a geometry compatible with S1A-mediated engagement.
