The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Clostridium botulinum neurotoxin b, "coiled-coil" domain
".

FunFam 2: Botulinum neurotoxin type D

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 8 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Zinc ion binding GO:0008270
Interacting selectively and non-covalently with zinc (Zn) ions.
5 P04958 (/IDA) P18640 (/IDA) P18640 (/IDA) P18640 (/IDA) P19321 (/IDA)
Ganglioside binding GO:0035594
Interacting selectively and non-covalently with a ganglioside, a ceramide oligosaccharide carrying in addition to other sugar residues, one or more sialic acid residues.
3 P18640 (/IDA) P18640 (/IDA) P18640 (/IDA)
Toxin activity GO:0090729
Interacting selectively with one or more biological molecules in another organism (the \target\ organism), initiating pathogenesis (leading to an abnormal, generally detrimental state) in the target organism. The activity should refer to an evolved function of the active gene product, i.e. one that was selected for. Examples include the activity of botulinum toxin, and snake venom.
3 P18640 (/IDA) P18640 (/IDA) P18640 (/IDA)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
2 A5JGM8 (/IPI) P04958 (/IPI)
Metalloendopeptidase activity GO:0004222
Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.
1 P04958 (/IMP)
Protein transmembrane transporter activity GO:0008320
Enables the transfer of a protein from one side of a membrane to the other.
1 P04958 (/EXP)
Protein transmembrane transporter activity GO:0008320
Enables the transfer of a protein from one side of a membrane to the other.
1 P19321 (/TAS)
Ganglioside GT1b binding GO:1905576
Interacting selectively and non-covalently with ganglioside GT1b.
1 P19321 (/IDA)

There are 3 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Negative regulation of neurotransmitter secretion GO:0046929
Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of a neurotransmitter.
4 P04958 (/IDA) P18640 (/IDA) P18640 (/IDA) P18640 (/IDA)
Membrane protein proteolysis GO:0033619
The proteolytic cleavage of a transmembrane protein leading to the release of its intracellular or ecto-domains.
3 P18640 (/IDA) P18640 (/IDA) P18640 (/IDA)
Negative regulation of calcium ion-dependent exocytosis GO:0045955
Any process that stops, prevents, or reduces the frequency, rate or extent of calcium ion-dependent exocytosis.
3 P18640 (/IDA) P18640 (/IDA) P18640 (/IDA)

There are 5 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Extracellular region GO:0005576
The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
1 P04958 (/TAS)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 P04958 (/TAS)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 P04958 (/TAS)
Endocytic vesicle membrane GO:0030666
The lipid bilayer surrounding an endocytic vesicle.
1 P04958 (/TAS)
Clathrin-coated endocytic vesicle membrane GO:0030669
