CRYSTAL STRUCTURE OF CLOSTRIDIUM BOTULINUM NEUROTOXIN B COMPLEXED WITH A TRISACCHARIDE
OverviewOverview
Clostridium botulinum neurotoxins are among the most potent toxins to, humans. The crystal structures of intact C. botulinum neurotoxin type B, (BoNT/B) and its complex with sialyllactose, determined at 1. 8 and 2.6 A, resolution, respectively, provide insight into its catalytic and binding, sites. The position of the belt region in BoNT/B is different from that in, BoNT/A; this observation presents interesting possibilities for designing, specific inhibitors that could be used to block the activity of this, neurotoxin. The structures of BoNT/B and its complex with sialyllactose, provide a detailed description of the active site and a model for, interactions between the toxin and its cell surface receptor. The latter, may provide valuable information for recombinant vaccine development.
