THE CRYSTAL SUFFERED FROM RADIATION DAMAGE DURING DATA COLLECTION.

0.1 M sodium cacodylate, pH 6.5, 6% w/v PEG3350, 0.3 M magnesium chloride, soaked in 20 mM 3'-sialyllactosamine, cryoprotection: 25% glycerol, VAPOR DIFFUSION, HANGING DROP, temperature 293K

THE BINDING SITES IN CHAINS B, C, H, J, K, O, Q, R AND S CONTAIN ONLY VERY WEAK ELECTRON DENSITY FEATURES FOR THE LIGAND. RESIDUES 71 AND 72 ADOPT MULTIPLE CONFORMATIONS IN THE STRUCTURE.
viral capsid protein, jelly roll, encapsidation, receptor binding, sialylated oligosaccharides, VIRAL PROTEIN
