The structure of a 64-residue scorpion toxin protein has been determined ab initio by the SnB program.

Ligand-Induced Conformational Changes in Poliovirus–Antiviral Drug Complexes

Capsid-binding antiviral compounds block the infectivity of poliovirus by stabilizing the native conformation of the mature virion. The virus structure is noticeably changed only when the least effective antivirals are bound.

X-ray Topography of Tetragonal Lysozyme Grown by the Temperature-Controlled Technique

X-ray diffraction topography has been employed to image growth-induced defects in tetragonal lysozyme crystals. Traditional diffraction studies were in good agreement with the topographic results. Crystals with fewer defects showed higher diffraction resolution.

Crystals of morphinone reductase from Pseudomonas putida M10, a flavoprotein involved in the degradation of morphine-like alkaloids have been obtained in space group I2₁2₁2₁. Preliminary molecular replacement calculations have been performed using Old Yellow Enzyme as a search model.

Improved diffraction of antithrombin crystals grown in microgravity

Microgravity crystallization of human antithrombin gave better ordered crystals with improved diffraction properties compared with earth-grown controls. This was assessed from single diffraction images using a novel algorithm that estimates the resolution of the Bragg scatter from single diffraction images, without requiring knowledge of the cell dimensions of the crystal.
