Function
function
Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
Miscellaneous
The Rieske protein is a high potential 2Fe-2S protein.
Catalytic activity
- a quinol + 2 Fe(III)-[cytochrome c](out) = a quinone + 2 Fe(II)-[cytochrome c](out) + 2 H+(out)
Cofactor
Note: Binds 1 [2Fe-2S] cluster per subunit.
