  • molecules
  • Two phospholipid molecules, one cardiolipin and one phosphatidylethanolamine, are also found in the SdhC and SdhD subunits (not shown in the image). (wikipedia.org)
  • stability

  • genes
  • These complex I genes have been associated with a variety of neurodegenerative disorders, including Leber's hereditary optic neuropathy (LHON), mitochondrial encephalomyopathy with stroke-like episodes (MELAS) and the previously mentioned Leigh syndrome. (wikipedia.org)
  • reduction
  • However, the currently accepted mechanism involves a rapid four-electron reduction involving immediate oxygen-oxygen bond cleavage, avoiding any intermediate likely to form superoxide. (wikipedia.org)
  • This causes a reduction in Complex I activity and disturbs its assembly. (wikipedia.org)
  • Iron-Sulfur
  • The side chains Thr254, His354, and Arg399 of subunit A stabilize the molecule while FAD oxidizes and carries the electrons to the first of the iron-sulfur clusters, [2Fe-2S]. (wikipedia.org)
  • The Iron-Sulfur electron tunneling system is shown in image 9. (wikipedia.org)
  • The two electrons released in the conversion of succinate to fumarate are transferred first to FAD, then to an iron-sulfur center and finally to CoQ. (orbitbiotech.com)
  • Lipids
  • These lipids typically form diether bilayer membranes similar to membranes of eukarya and bacteria. (hindawi.com)
  • proteins
  • The ability to transport proteins across membranes is vital for cell viability. (hindawi.com)
  • The high coverage of the photosynthetic apparatus and the identification of known hydrophobic proteins with low expression levels, such as cpSecE, Ohp1, and Ohp2, indicate an excellent dynamic resolution of the analysis. (plantcell.org)
  • transfer
  • All edge-to-edge distances between the centers are less than the suggested 14 Å limit for physiological electron transfer. (wikipedia.org)
  • This electron transfer is demonstrated in image 8. (wikipedia.org)
  • Absorption of visible light by a chromophore molecule is known to induce transfer of an electron from the main orbital (S0) to one of the singlet (S1 * , S2 * …) or triplet (T) excited orbitals (Fig. 2.2). (slideshare.net)
  • physiological
  • However, the plant enzyme has structural and functional features that set it apart from its counterparts in other organisms, raising questions about the physiological significance of this complex in plants. (plantphysiol.org)
  • Krebs
  • Acetyl-CoA, main product of the Pyruvate Dehydrogenase Complex in aerobic respiration, starts the Krebs cycle. (wikibooks.org)
  • biogenesis
  • The biogenesis, maintenance, and regulated breakdown of these photosynthetic complexes are very complex processes. (plantcell.org)
  • Cryo-EM reconstruction of the Arx1 particle at 11.9-Å resolution reveals regions of extra density on the pre-60S particle attributed to associated biogenesis factors, confirming the immature state of the nascent subunit. (biomedsearch.com)
