Cytochrome b-c1 complex subunit Rieske, transmembrane domain (IPR004192)

Short name: Rieske_TM

Overlapping homologous superfamilies

Domain relationships



The ubiquinol cytochrome c reductase (cytochrome bc1) complex is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The bc1 complex contains 11 subunits, 3 respiratory subunits (cytochrome B, cytochrome C1, Rieske protein), 2 core proteins and 6 low-molecular weight proteins [PMID: 9651245]. Each subunit of the cytochrome bc1 complex provides a single helix to make up the transmembrane region of the complex.

This entry represents the transmembrane domain of the iron-sulfur subunit Rieske.
