Abstract excerpt
Subunit 7 of the yeast cytochrome bc1 complex is encoded by the nuclear QCR7 gene and is essential for respiration. This protein does not contain a cleavable N-terminal mitochondrial targeting sequence, and it is not understood how the Qcr7 protein is imported into mitochondria and assembled into...
