SCOPe 2.06: Domain d1sqvc2: 1sqv C:2-260

Lineage for d1sqvc2 (1sqv C:2-260)

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 Cow (Bos taurus) [TaxId:9913] [81638] (18 PDB entries)
   Uniprot P00157

8. Domain d1sqvc2: 1sqv C:2-260 [119025]
   Other proteins in same PDB: d1sqva1, d1sqva2, d1sqvb1, d1sqvb2, d1sqvc1, d1sqvd1, d1sqvd2, d1sqve1, d1sqve2, d1sqvf_, d1sqvg_, d1sqvh_, d1sqvi_, d1sqvj_, d1sqvk_
