SCOPe 2.07: Domain d1kb9c2: 1kb9 C:1-261

Lineage for d1kb9c2 (1kb9 C:1-261)

Root: SCOPe 2.07
Class f: Membrane and cell surface proteins and peptides [56835] (60 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

Protein Mitochondrial cytochrome b subunit, N-terminal domain [81641] (3 species)
also includes extra transmembrane (linker) helix absent in plants and cyanobacteria subunits
Species Baker's yeast (Saccharomyces cerevisiae) [TaxId:4932] [81640] (5 PDB entries)

Domain d1kb9c2: 1kb9 C:1-261 [77316]
