General annotation (Comments)

Function

This is the heme-containing component of the cytochrome b-c1 complex, which accepts electrons from Rieske protein and transfers electrons to cytochrome c in the mitochondrial respiratory chain.

Subunit structure

Fungal 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 By similarity.

Subcellular location

Mitochondrion inner membrane; Single-pass membrane protein; Intermembrane side.

Post-translational modification

Binds 1 heme group per subunit.

Sequence similarities

Belongs to the cytochrome c family.

Contains 1 cytochrome c domain.

Sequence caution

The sequence EAA34520.1 differs from that shown. Reason: Frameshift at position 316.
