SCOPe 2.08: Domain d2d2ca1: 2d2c A:13-214

Lineage for d2d2ca1 (2d2c A:13-214)

1. Root: SCOPe 2.08

2. Class f: Membrane and cell surface proteins and peptides [56835] (69 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
