General annotation (Comments)

Function

Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain that generates an electrochemical potential coupled to ATP synthesis. The complex couples electron transfer from ubiquinol to cytochrome c. COR1 may mediate formation of the complex between cytochromes c and c1.

Subunit structure

Fungi cytochrome b-c1 complex contains 10 subunits; 3 respiratory subunits, 2 core proteins and 5 low-molecular weight proteins. Cytochrome b-c1 complex is a homodimer.

Subcellular location

Mitochondrion inner membrane.

Miscellaneous

Present with 19300 molecules/cell in log phase SD medium. Ref.6

Sequence similarities

Belongs to the peptidase M16 family. UQCRC1/QCR1 subfamily.

Caution

Does not seem to have a protease activity as it lack the zinc-binding site.
