The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

"
Fumarate reductase/succinate dehydrogenase, transmembrane subunit
".

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 3 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
Heme binding GO:0020037
Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.
2 Q7SGY6 (/ISS) Q9P7X0 (/ISS)
Ubiquinone binding GO:0048039
Interacting selectively and non-covalently with ubiquinone, a quinone derivative with a tail of isoprene units.
2 Q7SGY6 (/ISS) Q9P7X0 (/ISS)
Protein anchor GO:0043495
Interacting selectively and non-covalently with both a protein or protein complex and a membrane, in order to maintain the localization of the protein at a specific location on the membrane.
1 Q9P7X0 (/NAS)

There are 1 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
Protein import into mitochondrial inner membrane GO:0045039
The process comprising the import of proteins into the mitochondrion from outside the organelle and their insertion into the mitochondrial inner membrane. The translocase of the outer membrane complex mediates the passage of these proteins across the outer membrane, after which they are guided by either of two inner membrane translocase complexes into their final destination in the inner membrane.
1 Q9P7X0 (/ISS)

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
Mitochondrial inner membrane GO:0005743
The inner, i.e. lumen-facing, lipid bilayer of the mitochondrial envelope. It is highly folded to form cristae.
2 Q7SGY6 (/ISS) Q9P7X0 (/ISS)
Mitochondrial respiratory chain complex II, succinate dehydrogenase complex (ubiquinone) GO:0005749
A protein complex located in the mitochondrial inner membrane that forms part of the mitochondrial respiratory chain. Contains the four polypeptide subunits of succinate dehydrogenase, flavin-adenine dinucleotide and iron-sulfur. Catalyzes the oxidation of succinate by ubiquinone. Connects the TCA cycle with the respiratory chain.
2 Q7SGY6 (/ISS) Q9P7X0 (/ISS)
Mitochondrion GO:0005739
A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
1 Q9P7X0 (/IDA)
Integral component of membrane GO:0016021
The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
1 Q9P7X0 (/ISS)
Mitochondrial inner membrane protein insertion complex GO:0042721
A multi-subunit complex embedded in the mitochondrial inner membrane that mediates insertion of carrier proteins into the inner membrane.
