Cytochrome b-c1 complex, subunit 6 (IPR003422)

Short name: Cyt_b-c1_6

Overlapping homologous superfamilies

Family relationships



The ubiquinol-cytochrome C reductase complex (cytochrome bc1 complex) is a respiratory multienzyme complex [PMID: 9651245]. The bc1 complex contains 11 subunits; 3 respiratory subunits (cytochrome B, cytochrome C1, Rieske protein), 2 core proteins and 6 low molecular weight proteins. This family represents the 'hinge' protein of the complex, subunit 6, which is thought to mediate formation of the cytochrome c1 and cytochrome c complex. Proteins in this entry from an alpha-helical hairpin.
