Protein: Mitochondrial cytochrome b subunit, N-terminal domain from Baker's yeast (Saccharomyces cerevisiae) [TaxId: 4932]

Lineage:

  1. Root: scop
  2. Class: Membrane and cell surface proteins and peptides [56835]
    Does not include proteins in the immune system
  3. Fold: Heme-binding four-helical bundle [81344]
    core: four transmembrane helices, up-and-down bundle, binds one or two heme groups in between the helices
  4. Superfamily: Transmembrane di-heme cytochromes [81342]
    Three of the four heme-ligands are conserved between the two families; both heme groups bind similarly but not identically

  5. Family: Cytochrome b of cytochrome bc1 complex (Ubiquinol-cytochrome c reductase) [81642]
    a part (domain) of a larger mitochondrial cytochrome b subunit, separate subunit in plants and cyanobacteria
  6. Protein: Mitochondrial cytochrome b subunit, N-terminal domain [81641]
    also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits
  7. Species: Baker's yeast (Saccharomyces cerevisiae) [TaxId: 4932] [81640]
