Unusual diffraction of type B influenza virus neuraminidase crystals.

Abstract

An unusual X-ray diffraction pattern by tetragonal crystals of a type B influenza virus neuraminidase was observed in that the odd-l reflections were missing or diffuse while the even-l reflections were sharp and strong. A statistical analysis showed that an error (epsilon) in the spacing of successive planes of neuraminidase molecules was randomly distributed along the c direction, which resulted in such an unusual diffraction pattern. The error epsilon follows the Bernoullian distribution and may be caused by a flexible loop on the top surface of the neuraminidase.
