Neuraminidase (NA) inhibitors are one of the two major classes of antivirals available for the treatment and prevention of influenza. X-ray crystal structure determination of NA head domains and their complexes with various inhibitors are of importance for the design and optimization of anti-influenza drugs. However, the globular tetrameric properties of NA head domains may produce crystals with pathological imperfections, lattice-translocation defects, making structure determination no longer straightforward. In this report, using a crystal of the NA head domain from the Wuhan Asiatic toad influenza virus as an example, the identification and solution of this type of crystal pathology are presented. Furthermore, its underlying mechanism of formation is explored.
