Protein: Cytochrome b6 subunit of the cytochrome b6f complex from Mastigocladus laminosus [TaxId: 83541]

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
   uperfamily
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: Cytochrome b6 subunit of the cytochrome b6f complex [103498]
7. Species: Mastigocladus laminosus [TaxId: 83541] [103499]
