Biological Activity of Heated Diphtheria Toxin [PDF]

open access: yesJournal of Bacteriology, 1973
Diphtheria toxin splits into two fragments when heated at 100 C for 10 min in a phosphate buffer. The separated fragments have molecular weights of 24,000 and 39,000, respectively. These molecular weights are similar to those of the A and B fragments found in diphtheria toxin preparations after thiol reduction.

Biological Toxins as the Potential Tools for Bioterrorism [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Biological toxins are a heterogeneous group produced by living organisms. One dictionary defines them as “Chemicals produced by living organisms that have toxic properties for another organism”. Toxins are very attractive to terrorists for use in acts of bioterrorism. The first reason is that many biological toxins can be obtained very easily.

Botulinum Neurotoxin Serotype A Recognizes Its Protein Receptor SV2 by a Different Mechanism than Botulinum Neurotoxin B Synaptotagmin

open access: yesToxins, 2016
Botulinum neurotoxins (BoNTs) exhibit extraordinary potency due to their exquisite neurospecificity, which is achieved by dual binding to complex polysialo-gangliosides and synaptic vesicle proteins.
