IPR016174 is a Di-haem cytochrome, transmembrane.
<p>This entry represents a haem-binding domain with a 4-helical bundle structure that is found in transmembrane di-haem cytochromes. The domain contains four transmembrane helices in an up-and-down bundle, and binds two haem groups in between the helices; three of the four haem-binding residues is conserved between family members. Proteins containing this domain include:</p> <ul> <li>N-terminal domain of mitochondrial cytochrome b subunit, in which the domain contains an extra transmembrane linker helix that is absent in plant and cyanobacteria subunits [[cite:PUB00037404]].</li> <li>Cytochrome b6 subunit of the cytochrome b6f complex, which provides the electronic connection between the photosystems I and II reaction centres of oxygenic photosynthesis, and generates a transmembrane electrochemical proton gradient for adenosine triphosphate synthesis [[cite:PUB00032072]].</li> <li>Cytochrome gamma subunit of formate dehydrogenase-N (Fdn-N), which acts as a major component of Escherichia coli nitrate respiration [[cite:PUB00009871]].</li> </ul> <p>Please note, this entry also identifies a number of proteins that are cleaved into two chains - a truncated non-functional cytochrome oxidase 1 and an intron-encoded endonuclease.</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
