Abstract
Cytochrome b-c1 complex subunit 9 (QCR9) 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. It may interact with cytochrome c1 [ 1 , 2 ]. QCR9 contains the single transmembrane helix structure.
