> According to wikipedia, it works by "cleaving key proteins required for nerve activation". Unless there's some self-replication mechanism, how does that even work? The toxin is an enzyme and as such is not consumed during the cleavage reaction. A molecule of the botulinum toxin breaks down one protein molecule and then moves on to the next one until the toxin itself is degraded by the organism.
