Electrophysiological Characterization of the Antarease Metalloprotease from Tityus serrulatus Venom. [PDF]

Toxins (Basel), 2017
Scorpions are among the oldest venomous living organisms and the family Buthidae is the largest and most medically relevant one. Scorpion venoms include many toxic peptides, but recently, a metalloprotease from Tityus serrulatus called antarease was reported to be capable of cleaving VAMP2, a protein involved in the neuroparalytic syndromes of tetanus ...
