This domain is responsible for the zinc-dependent proteolytic activity of the toxin, specifically cleaving the VAMP2 protein between Trp89 and Trp90. The domain contains the conserved HExxH zinc-binding motif characteristic of the M27 metalloproteases family, but features a wider, more open and negatively charged catalytic pocket compared to other botulinum neurotoxins. It also contains a unique beta-hairpin motif (residues 31-60) and an unusually interrupted alpha-helix (residues 309-350) with an extended loop. The crystal structure revealed an additional calcium ion near the active site that may be involved in substrate binding.
