If you mean the neurotoxins, recent work has shown them to be zinc
metalloproteases that enter nerve cells and block neurotransmitter
release via zinc-dependent cleavage of proteins involved in neuroexocytosis.
Here's a recent review:
Montecucco, C, and Schiavo, G. 1994. Mechanism of action of
tetanus and botulinum neurotoxins. Mol. Microbiol. 13:1-8.
There have been several additional articles since this review, expanding
on the specificity for each of the antigenically distinct botulinum
neurotoxins (look up the same authors).
