SCOP 1.73: Species: Chlamydomonas reinhardtii [TaxId: 3055]

Root: SCOP 1.73
Class f: Membrane and cell surface proteins and peptides [56835] (50 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] (2 proteins)
a part (domain) of a larger mitochondrial cytochrome b subunit, separate subunit in plants and cyanobacteria

Protein Cytochrome b6 subunit of the cytochrome b6f complex [103498] (2 species)
Species Chlamydomonas reinhardtii [TaxId:3055] [103500] (1 PDB entry)
