The light chain of tetanus neurotoxin (TeNT) is a zinc-dependent metalloprotease which specifically cleaves the synaptic vesicle protein synaptobrevin. This crucial mechanism of tetanus toxicity leads to a blockade of inhibitory neurotransmitter release. We recently reported the development of a highly sensitive endopeptidase assay for the specific in vitro(More)
Tetanus neurotoxin (TeNT(1)) is a bacterial protease which specifically cleaves the vesicle protein synaptobrevin-2 (vesicle associated membrane protein-2, VAMP-2). This proteolytic feature of the toxin has been used to develop a sensitive endopeptidase assay for the detection of TeNT activity as an alternative to the in vivo assay for TeNT toxicity.(More)
Botulinum neurotoxins (BoNTs) are the most potent toxins known. However, the paralytic effect caused by BoNT serotypes A and B is taken advantage of to treat different forms of dystonia and in cosmetic procedures. Due to the increasing areas of application, the demand for BoNTs A and B is rising steadily. Because of the high toxicity, it is mandatory to(More)
