N-junction
Description
The N-junction is a junction for convergent electron flow in the electron transfer pathway (ET-pathway) from type N substrates (further details »N-pathway control state) through the mt-NADH pool to Complex I (CI), and further transfer through the Q-junction to Complex III (CIII). Representative type N substrates are pyruvate (P), glutamate (G) and malate (M). The corresponding dehydrogenases (PDH, GDH, MDH) and some additional TCA cycle dehydrogenases (isocitrate dehydrogenase, oxoglutarate dehydrogenase generate NADH, the substrate of Complex I (CI). The concept of the N-junction and F-junction provides a basis for defining categories of SUIT protocols based on Electron-transfer-pathway states.
