Function
function
Component of the ubiquinol-cytochrome c oxidoreductase, a multisubunit transmembrane complex that is part of the mitochondrial electron transport chain which drives oxidative phosphorylation (PubMed:34525326, PubMed:36923588).
The complex plays an important role in the uptake of multiple carbon sources present in different host niches (PubMed:36923588).

Interaction
Subunit
Component of the ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII), a multisubunit enzyme composed of 10 subunits. The complex is composed of 3 respiratory subunits cytochrome b (COB), cytochrome c1 (CYT1) and Rieske protein (RIP1), 2 core protein subunits COR1 and QCR2, and 5 low-molecular weight protein subunits QCR6, QCR7, QCR8, QCR9 and QCR10. The complex exists as an obligatory dimer and forms supercomplexes (SCs) in the inner mitochondrial membrane with a monomer or a dimer of cytochrome c oxidase (complex IV, CIV), resulting in 2 different assemblies (supercomplexes III2IV and III2IV2).
