SCOPe 2.06: Domain d1ezvc3: 1ezv C:1-261

Lineage for d1ezvc3 (1ezv C:1-261)

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 Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [81640] (5 PDB entries)

8. Domain d1ezvc3: 1ezv C:1-261 [75834]
   Other proteins in same PDB: d1ezva1, d1ezva2, d1ezvb1, d1ezvb2, d1ezvc2, d1ezvd1, d1ezvd2, d1ezve1, d1ezve2, d1ezvf_, d1ezvg_, d1ezvh_, d1ezvi_, d1ezvx_, d1ezvy_
   complexed with fes, hem, sma, uq6
