Crystallization and preliminary X-ray studies of influenza A virus neuraminidase of subtypes N5, N6, N8 and N9.
Taylor G., Garman E., Webster R., Saito T., Laver G.
Neuraminidase heads from the following subtypes of influenza A virus have been crystallized: N5, N6, N8 and whale virus N9. The last three yielded crystals of X-ray diffraction quality; the N5 crystals obtained so far are not suitable for high resolution studies. The cell dimensions and space groups of crystals grown from the four subtypes have been determined.
