Cytochromes are haem-containing proteins that function as electron carriers during electron transfer reactions. Cytochromes can be divided into types depending upon how the haem atom is bound: in c-type cytochromes the haem is covalently attached to the polypeptide, while in b-type cytochromes the haem is not covalently attached. A four-helical bundle motif is found in several cytochromes, including the cytochrome c family , cytochrome b562 , and cytochrome b559, despite having very low sequence similarities. Cytochromes c and b562 are found in many bacteria and are probably involved in nitric oxide transfer . These proteins exhibit a reduction potential in the range of around żżż8mV to 400mV, which sets the energy yield possible in metabolism and is also a key determinant of the rate at which redox reactions proceed .

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry
out SCOP domain assignments to all genomes at the superfamily level.
Alignments of sequences to 9 models
in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical
are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.
Browse and view proteins in genomes which have
different domain combinations including a Cytochromes domain.
Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.
Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.
There are 9 hidden Markov models representing the Cytochromes superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
