Summary: Clostridium neurotoxin, N-terminal receptor binding
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
Clostridium neurotoxin, N-terminal receptor binding Provide feedback
The Clostridium neurotoxin family is composed of tetanus neurotoxin and seven serotypes of botulinum neurotoxin. The structure of the botulinum neurotoxin reveals a four domain protein. The N-terminal catalytic domain (PF01742), the central translocation domains and two receptor binding domains . This domains is the N-terminal receptor binding domain,which is comprised of two seven-stranded beta-sheets sandwiched together to form a jelly role motif . The role of this domain in receptor binding appears to be indirect.

The Clostridium neurotoxin family is composed of tetanus neurotoxin and seven serotypes of botulinum neurotoxin. The structure of the botulinum neurotoxin reveals a four domain protein. The N-terminal catalytic domain (INTERPRO), the central translocation domain and two receptor binding domains [PUBMED:9783750]. This domain is the N-terminal receptor binding domain, which is comprised of two seven-stranded beta-sheets sandwiched together to form a jelly role motif [PUBMED:9783750]. The role of this domain in receptor binding appears to be indirect.

This superfamily includes a diverse range of carbohydrate binding domains and glycosyl hydrolase enzymes that share a common structure.
The clan contains the following 16 members:DUF1080 DUF2401 Gal-bind_lectin Glyco_hydro_11 Glyco_hydro_12 Glyco_hydro_16 Glyco_hydro_7 Laminin_G_1 Laminin_G_2 Laminin_G_3 Lectin_leg-like Lectin_legB Pentaxin Sialidase SKN1 Toxin_R_bind_N
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

You can use the tree controls to manipulate how the interactive tree is displayed:
- show/hide the summary boxes
- highlight species that are represented in the seed alignment
- expand/collapse the tree or expand it to a given depth

- save a plain text representation of the tree
There are 2 interactions for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Toxin_R_bind_N domain has been found. There are 77 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
