1. Alternative NAD(P)H dehydrogenases in plant mitochondria - localisation, catalytic functions and physiological roles
Abstract : In addition to complex I, the plant mitochondrial electron transport chain possesses several alternative NAD(P)H dehydrogenases, not present in animals. These enzymes allow nonenergy-conserving electron transfer from cytoplasmic and matrix NAD(P)H to ubiquinone. READ MORE

2. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases
Abstract : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. READ MORE

3. Plant type II NAD(P)H dehydrogenases : Structure, regulation and evolution of NDB proteins
Abstract : In living organisms, respiration is a biological process degrading different carbon substrates, consuming O2, and releasing the carbon as CO2. Plants have several alternative enzymes that are involved in the respiratory processes, as compared to animals. READ MORE

4. Pyridine Nucleotides in Plant Mitochondria. Amounts, metabolism and contribution to electron transport
Abstract : HPLC analysis was used for direct quantification of amounts and redox levels of pyridine nucleotides in plant mitochondria. The amount of NAD(H) and NADP+ varied, 1.0-3.7 and 0-0. READ MORE

5. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways
Abstract : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. READ MORE
