SCOPe 2.03: Protein: automated matches

Root: SCOPe 2.03
Class f: Membrane and cell surface proteins and peptides [56835] (57 folds)
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
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

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

Domain for 4i7z:

Domain d4i7za_: 4i7z A: [196846]
Other proteins in same PDB: d4i7zb_, d4i7zc1, d4i7zc2, d4i7zc3, d4i7ze_, d4i7zf_, d4i7zg_, d4i7zh_
automated match to d2e74a1
complexed with 1e2, 8k6, bcr, cd, cla, hem, mys, oct, oz2, umq
