SCOPe 2.06: Domain d2bccc3: 2bcc C:2-261

Lineage for d2bccc3 (2bcc C:2-261)

1. Root: SCOPe 2.06

2. Class f: Membrane and cell surface proteins and peptides [56835] (59 folds)

3. Fold f.21: Heme-binding four-helical bundle [81344] (3 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] (3 proteins)
   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 Chicken (Gallus gallus) [TaxId:9031] [81639] (8 PDB entries)

8. Domain d2bccc3: 2bcc C:2-261 [75988]
   Other proteins in same PDB: d2bcca1, d2bcca2, d2bccb1, d2bccb2, d2bccc2, d2bccd2, d2bccd3, d2bcce1, d2bcce2, d2bccf_, d2bccg_, d2bcch_, d2bccj_
   complexed with bog, fes, hem, pee, sig, u10
