VISITING SPEAKER: The mitochondrial NADH dehydrogenase complex of plants: Function in respiration and photosynthesis

* Login to add events... *
Today's date is Tuesday, October 15, 2019
The mitochondrial NADH dehydrogenase complex of plants: Function in respiration and photosynthesis : The mitochondrial NADH dehydrogenase complex (complex I) is the largest enzyme complex of the Oxidative Phosphorylation (OXPHOS) system and the main entrance site for electrons into the respiratory electron transfer chain. Other events...
Complex I has several unique features in plants. Most notably, it includes 15 extra subunits, some of which introduce side activities into this respiratory enzyme. For example, subunits resembling an archaebacterial gamma-type carbonic anhydrase form an integral part of complex I in plants. These carbonic anhydrase subunits constitute a spherical extra domain which is attached to the membrane arm of complex I on its matrix exposed side. Furthermore, L-galactono-1,4 dehydrogenase (GLDH), which catalyses the terminal step of ascorbate biosynthesis in plants, is associated with complex I in plants. Novel data on the structure of the NADH dehydrogenase complex and its multiple functions in plant cells will be presented and discussed.
