P46269 - QCR8_SOLTU

Protein

Cytochrome b-c1 complex subunit 8

Gene
N/A
Organism
Solanum tuberosum (Potato)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli
  1. Functioni

    This is a component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is part of the mitochondrial respiratory chain. This subunit, together with cytochrome b, binds to ubiquinone.
