Function

[TETX_CLOTE] Tetanus toxin acts by inhibiting neurotransmitter release. It binds to peripheral neuronal synapses, is internalized and moves by retrograde transport up the axon into the spinal cord where it can move between postsynaptic and presynaptic neurons. It inhibits neurotransmitter release by acting as a zinc endopeptidase that catalyzes the hydrolysis of the '76-Gln-|-Phe-77' bond of synaptobrevin-2.

Publication Abstract from PubMed

Clostridial neurotoxins are comprised of botulinum (BoNT) and tetanus (TeNT), which share significant structural and functional similarity. Crystal structures of the binding domain of TeNT complexed with disialyllactose (DiSia) and a tri-peptide Tyr-Glu-Trp (YEW) have been determined to 2.3 and 2.2 A, respectively. Both DiSia and YEW bind in a shallow cleft region on the surface of the molecule in the beta-trefoil domain, interacting with a set of common residues, Asp1147, Asp1214, Asn1216, and Arg1226. DiSia and YEW binding at the same site in tetanus toxin provides a putative site that could be occupied either by a ganglioside moiety or a peptide. Soaking experiments with a mixture of YEW and DiSia show that YEW competes with DiSia, suggesting that YEW can be used to block ganglioside binding. A comparison with the TeNT binding domain in complex with small molecules, BoNT/A and /B, provides insight into the different modes of ganglioside binding.
