Liu, Yun-Jun, Norberg, Fredrik E. B., Szilágyi, Anna, De Paepe, Rosine, Åkerlund, Hans-Erik, Rasmusson, Allan G.

Plant mitochondria contain alternative external NAD(P)H dehydrogenases, which oxidize cytosolic NADH or NADPH and reduce ubiquinone without inherent linkage to proton pumping and ATP production. In...

Antimycin A treatment decreases respiratory internal rotenone-insensitive NADH oxidation capacity in potato leaves (2004)

Geisler, Daniela A, Johansson, Fredrik I, Svensson, Å Staffan, Rasmusson, Allan G

Abstract Background The plant respiratory chain contains several energy-dissipating enzymes, these being type II NAD(P)H dehydrogenases and the alternative oxidase, not present in mammals. The...

Cold stress decreases the capacity for respiratory NADH oxidation in potato leaves. (2002)

Svensson, A Staffan, Johansson, Fredrik I, Møller, Ian M, Rasmusson, Allan G

Cold stress effects on the expression of genes for respiratory chain enzymes were investigated in potato (Solanum tuberosum L., cv. Desiree) leaves. The nda1 and ndb1 genes, homologues to genes...

Molecular Characterisation of the 76 kDa Iron-Sulphur Protein Subunit of Potato Mitochondrial Complex I (1998)

Rasmusson, Allan G., Heiser, Volker, Irrgang, Klaus D., Brennicke, Axel, Grohmann, Lutz

Genes encoding subunits of complex I (EC 1.6.5.3) of the mitochondrial respiratory chain vary in their locations between the mitochondrial and nuclear genomes in different organisms, whereas genes...

Arabidopsis Genes Encoding Mitochondrial Type II NAD(P)H Dehydrogenases Have Different Evolutionary Origin and Show Distinct Responses to Light1

Michalecka, Agnieszka M., Svensson, Å. Staffan, Johansson, Fredrik I., Agius, Stephanie C., Johanson, Urban, Brennicke, Axel, ...

In addition to proton-pumping complex I, plant mitochondria contain several type II NAD(P)H dehydrogenases in the electron transport chain. The extra enzymes allow the nonenergy-conserving electron...

Light Regulation of the Arabidopsis Respiratory Chain. Multiple Discrete Photoreceptor Responses Contribute to Induction of Type II NAD(P)H Dehydrogenase Genes1

Escobar, Matthew A., Franklin, Keara A., Svensson, Å. Staffan, Salter, Michael G., Whitelam, Garry C., Rasmusson, Allan G.

Controlled oxidation reactions catalyzed by the large, proton-pumping complexes of the respiratory chain generate an electrochemical gradient across the mitochondrial inner membrane that is harnessed...

NADP-Utilizing Enzymes in the Matrix of Plant Mitochondria 1

Rasmusson, Allan G., Møller, Ian M.

Purified potato tuber (Solanum tuberosum L. cv Bintie) mitochondria contain soluble, highly latent NAD+- and NADP+-isocitrate dehydrogenases, NAD+- and NADP+-malate dehydrogenases, as well as an...

Oxidation of External NAD(P)H by Purified Mitochondria from Fresh and Aged Red Beetroots (Beta vulgaris L.) 1

Fredlund, Kenneth M., Rasmusson, Allan G., Møller, Ian M.

Mitochondria were isolated from fresh beetroots (Beta vulgaris L. cvs Rubria and Nina) by differential centrifugation followed by Percoll gradient centrifugation. These purified mitochondria oxidized...

Oxidation and reduction of pyridine nucleotides in alamethicin-permeabilized plant mitochondria.

Johansson, Fredrik I, Michalecka, Agnieszka M, Møller, Ian M, Rasmusson, Allan G

The inner mitochondrial membrane is selectively permeable, which limits the transport of solutes and metabolites across the membrane. This constitutes a problem when intramitochondrial enzymes are...
