General annotation (Comments)

Function

Component of the green S-bacteria bc-complex which consists of the Rieske protein and cytochrome b subunit and which appears to lack a cytochrome c1-equivalent. This complex has a comparatively low redox potential.

Catalytic activity

Plastoquinol-1 + 2 oxidized plastocyanin = plastoquinone + 2 reduced plastocyanin.

Cofactor

Binds 1 2Fe-2S cluster per subunit By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein Potential.

Miscellaneous

The Rieske protein is a high potential 2Fe-2S protein.

Sequence similarities

Contains 1 Rieske domain.
