===Parainfluenza Virus 5 (SV5) Hemagglutinin-Neuraminidase (HN) with ligand DANA (soaked with DANA, pH8.0)===

~~==Overview==~~

<!--

The ~~paramyxovirus hemagglutinin-neuraminidase (HN) functions in virus attachment to cells~~, ~~cleavage of sialic acid from oligosaccharides~~, ~~and stimulating membrane fusion during virus entry into cells. The structural basis for these diverse functions remains~~ to ~~be fully understood. We report~~ the ~~crystal structures of the parainfluenza virus 5~~ (~~SV5) HN and its complexes with sialic acid, the inhibitor DANA, and the receptor sialyllactose~~. ~~SV5 HN shares common structural features with HN of Newcastle disease virus (NDV) and human parainfluenza 3 (HPIV3~~), ~~but unlike the previously determined HN structures, the SV5 HN forms a tetramer in solution, which~~ is ~~thought to be~~ the physiological oligomer. The sialyllactose complex reveals intact receptor within the active site, but no major conformational changes in the protein. The SV5 HN structures do not support previously proposed models for HN action in membrane fusion and suggest alternative mechanisms by which HN may promote virus entry into cells.
