Q-junction
Description
The Q-junction is a junction for convergent electron flow in the electron transfer system (ETS) from Complex I (CI), Complex II (CII), electron-transferring flavoprotein (CETF), glycerophosphate dehydrogenase complex (CGpDH), choline dehydrogenase and other enzyme complexes into the Q-cycle (ubiquinol/ubiquinone), and further to Complex III (CIII).
