BoNT-C1 (Botulinum Neurotoxin Type C1 [Heavy Chain]) is a 100kD C-terminal fragment of the C1 Clostridum botulinum neurotoxin (holo)precursor.
It constitutes a nonenzymatic part of a Zn 2+ -dependent M27 family endoprotease that potently blocks neurosecretion.
The inactive 1291aa, 150kD C1 precursor is cleaved between Lys449Thr450 to generate a heterodimeric toxin held together by a preexisting interchain disulfide bond between Cys437 and Cys453.
The 100kD C-terminus (heavy chain) acts as a ligand for neuronal membrane ecto-acceptors, its inducing internalization with translocation.
The 50kD N-terminal light chain acts as an intracellular peptidase that cleaves SNAP-25 and syntaxin.
This is suggested to block noradrenalin release from a readily releasable pool of vesicles.
Over aa866-1291, the C1 heavy chain shares less than 40% aa identity with the D-type neurotoxin heavy chain.
