SCOP 1.63: Domain d1bgyo3: 1bgy O:1-260

Lineage for d1bgyo3 (1bgy O:1-260)

1. Root: SCOP 1.63

2. Class f: Membrane and cell surface proteins and peptides [56835] (34 folds)

3. Fold f.21: Heme-binding four-helical bundle [81344] (2 superfamilies)
   core: four transmembrane helices, up-and-down bundle, binds one or two heme groups in between the helices

4. Superfamily f.21.1: Transmembrane di-heme cytochromes [81342] (2 families)
   Three of the four heme-ligands are conserved between the two families; both heme groups bind similarly but not identically

5. Family f.21.1.2: Cytochrome b of cytochrome bc1 complex (Ubiquinol-cytochrome c reductase) [81642] (1 protein)
   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] (3 species)
   also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits

7. Species Cow (Bos taurus) [TaxId:9913] [81638] (3 PDB entries)

8. Domain d1bgyo3: 1bgy O:1-260 [75810]
