Botulinum toxin causes flaccid paralysis by inhibiting neurotransmitter (acetylcholine) release from the presynaptic membranes of nerve terminals of eukaryotic host skeletal and autonomic nervous system, with frequent heart or respiratory failure. Precursor of botulinum neurotoxin X which has 2 coreceptors; complex polysialylated gangliosides found on neural tissue and specific membrane-anchored proteins found in synaptic vesicles. Receptor proteins are exposed on host presynaptic cell membrane during neurotransmitter release, when the toxin heavy chain (HC) binds to them. Upon synaptic vesicle recycling the toxin is taken up via the endocytic pathway. When the pH of the toxin-containing endosome drops a structural rearrangement occurs so that the N-terminus of HC forms pores that allows the light chain (LC) to translocate into the cytosol. Once in the cytosol the disulfide bond linking the 2 subunits is reduced and LC cleaves its target protein on synaptic vesicles, preventing their fusion with the cytoplasmic membrane and thus neurotransmitter release (By similarity). Artificially assembled BoNT/X cleaves synaptobrevin-2/VAMP2 and VAMP4 in cultured rat neurons and causes flaccid paralysis in mice (PubMed:28770820).By similarity1 Publication
Has proteolytic activity. After translocation into the eukaryotic host cytosol, LC hydrolyzes the '66-Arg-|-Ala-67' bond in synaptobrevin-2/VAMP2, and the equivalent bonds in 'Arg-|-Ala' bonds in VAMP1 and VAMP3, thus blocking neurotransmitter release (PubMed:28770820). Has a wider target range than most BoNTs, as it also cleaves the '87-Arg-|-Ser-89' bond in VAMP4, the '40-Arg-|-Ser-41' bond in VAMP5 and the '173-Lys-|-Ser-174' bond in YKT6; whether these are physiologically relevant substrates is unknown (PubMed:28770820). BoNT/X is 10-fold more efficient than BoNT/B and 40-fold more efficient than TeTX on an artificial human VAMP1 substrate (PubMed:29540745).2 Publications
Responsible for epithelial cell transcytosis, host nerve cell targeting and translocation of light chain (LC) into host cytosol. Composed of 3 subdomains; the translocation domain (TD), and N-terminus and C-terminus of the receptor-binding domain (RBD). The RBD is responsible for the adherence of the toxin to the cell surface. It simultaneously recognizes 2 coreceptors; polysialated gangliosides and an unknown receptor protein in close proximity on host synaptic vesicles. The N-terminus of the TD wraps an extended belt around the perimeter of the LC, protecting Zn2+ in the active site (By similarity). The TD inserts into synaptic vesicle membrane to allow translocation into the host cytosol (By similarity). Protein ligation of the RBD to the rest of the toxin (creates an artificial whole toxin) greatly increases VAMP2 degradation, and thus neuron uptake (PubMed:28770820).By similarity1 Publication

Miscellaneous

There are seven antigenically distinct forms of botulinum neurotoxin: Types A, B, C, D, E, F, and G; new subtypes are quite frequent. This toxin is not recognized or neutralized by any of the antisera against the standard serotypes (PubMed:28770820).1 Publication
Botulism poisoning is usually food-borne, either by ingesting toxin or bacterial-contaminated food, or less frequently by inhalation poisoning. In both cases the neurotoxin binds to the apical surface of epithelial cells in the gut or airway. Toxin undergoes receptor-mediated endocytosis (using a different receptor than on target nerve cells), transcytosis across the epithelial cells and release into the general circulation. Once in the general circulation it binds to its target cells.By similarity
This strain was isolated from an infant botulism patient in Japan in 1996; toxicity of this strain is due to a type B neurotoxin (PubMed:8942019). This locus has includes a number of other genes usually associated with the botulinum neurotoxin cluster in Clostridia (p47, hemagglutinin genes and the OrfX cluster), which should permit the toxin to survive in a host. It remains unknown whether BoNT/X is ever produced in C.botulinum strain 111.1 Publication1 Publication

    <p>This subsection of the ‘Entry information’ section provides a mnemonic identifier for a UniProtKB entry, but it is not a stable identifier. Each reviewed entry is assigned a unique entry name upon integration into UniProtKB/Swiss-Prot.<p><a href='/help/entry_name' target='_top'>More...</a></p>Entry nameiBXX_CLOBO
    <p>This subsection of the ‘Entry information’ section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called ‘Primary (citable) accession number’.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P0DPK1
    <p>This subsection of the ‘Entry information’ section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification (‘Last modified’). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical_and_isoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: July 18, 2018

    This is version 6 of the entry and version 1 of the sequence. See complete history.
    <p>This subsection of the ‘Entry information’ section indicates whether the entry has been manually annotated and reviewed by UniProtKB curators or not, in other words, if the entry belongs to the Swiss-Prot section of UniProtKB (<strong>reviewed</strong>) or to the computer-annotated TrEMBL section (<strong>unreviewed</strong>).<p><a href='/help/entry_status' target='_top'>More...</a></p>Entry statusiReviewed (UniProtKB/Swiss-Prot)
