Class a: All alpha proteins [46456] (218 folds) |
Fold a.138: Multiheme cytochromes [48694] (1 superfamily) variable number of helices and little beta structure; not a true fold |
Superfamily a.138.1: Multiheme cytochromes [48695] (3 families) duplication: contains multiple CxxCH motifs |
a.138.1.1: Cytochrome c3-like [48696] (4 proteins) |
a.138.1.2: Photosynthetic reaction centre (cytochrome subunit) [48707] (1 protein) consists of four heme-binding repeats |
a.138.1.3: Di-heme elbow motif [48711] (7 proteins) the main characteristic feature of this motif is the packing of its two hemes many members contains one or more complete motifs flanked by incomplete motifs and/or other domains |
