How just drops of viper venom pack a deadly punch

(American Society for Biochemistry and Molecular Biology) Researchers at Brazil's largest producer of antivenoms report a structural analysis of glycans modifying venom proteins in several species of lancehead viper. The snakes are among the most dangerous in South America. The report offers insight into the solubility and stability of toxic proteins from venom, and into how venoms from different species vary. Scientists are now working to map glycan structures back onto the proteins they modify.
