1. 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

2. 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

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. Respiratory NAD(P)H dehydrogenases of plants - Gene identity and expression in response to light and cold
Abstract : The respiratory chain of plants contains class 2 NAD(P)H dehydrogenases, not present in animals. The functional roles of these enzymes have been elusive for a long time. Two cDNAs, homologous to class 2 NADH dehydrogenase genes of yeast and E. coli, were isolated from potato leaves. READ MORE

5. Alternative pathways in the plant respiratory chain -transgenic analyses of type II NAD(P)H dehydrogenases
Abstract : During oxidative phosphorylation, the production of ATP is driven by the activity of several proton-pumping respiratory protein complexes. In plants, non-proton pumping type II NAD(P)H dehydrogenases are also present in the respiratory chain to oxidize cytosolic and matrix NAD(P)H. READ MORE
