Vitamin K2 in Electron Transport System: Are Enzymes Involved in Vitamin K2 Biosynthesis Promising Drug Targets?

open access: yesMolecules, 2010
Aerobic and anaerobic respiratory systemsallow cells to transport the electrons to terminal electron acceptors. The quinone (ubiquinone or menaquinone) pool is central to the electron transport chain. In the majority of Gram-positive bacteria, vitamin K2

Endurance exercise training in pulmonary hypertension increases skeletal muscle electron transport chain supercomplex assembly

open access: yesPulmonary Circulation, 2020
Pulmonary hypertension is associated with pronounced exercise intolerance (decreased V ċ O 2 max) that can significantly impact quality of life. The cause of exercise intolerance in pulmonary hypertension remains unclear. Mitochondrial supercomplexes are

The Significance of Chloroplast NAD(P)H Dehydrogenase Complex and Its Dependent Cyclic Electron Transport in Photosynthesis

open access: yesFrontiers in Plant Science, 2021
Chloroplast NAD(P)H dehydrogenase (NDH) complex, a multiple-subunit complex in the thylakoid membranes mediating cyclic electron transport, is one of the most important alternative electron transport pathways.

Coordinating Electron Transport Chains to an Electron Donor

open access: yesOrganic Letters, 2015
Two electron transport chains (2 and 3) featuring two fullerenes with different electron acceptor strengths have been synthesized, characterized, and coordinated to a light harvesting/electron donating zinc porphyrin. Electrochemical assays corroborate the redox gradients along the designed electron transport chains, and complementary absorption and ...

Iron deficiency induces changes in riboflavin secretion and the mitochondrial electron transport chain in hairy roots of Hyoscyamus albus. [PDF]

open access: yes, 2010
Hyoscyamus albus hairy roots secrete riboflavin under Fe-deficient conditions. To determine whether this secretion was linked to an enhancement of respiration, both riboflavin secretion and the reduction of 2,3,5-triphenyltetrazolium chloride (TTC), as a

Arrangement of electron transport chain components in bovine mitochondrial supercomplex I1III2IV1 [PDF]

open access: yes, 2011
The respiratory chain in the inner mitochondrial membrane contains three large multi-enzyme complexes that together establish the proton gradient for ATP synthesis, and assemble into a supercomplex.

Mitochondrial Complex Abundance, Mitophagy Proteins, and Physical Performance in People With and Without Peripheral Artery Disease

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Mitochondrial abnormalities exist in gastrocnemius muscle of people with peripheral artery disease (PAD). Whether abnormalities in mitochondrial biogenesis and autophagy are associated with greater ischemia or walking impairment in PAD is ...

Computational study of electron transport in [FeFe] hydrogenase enzymes [PDF]

open access: yes, 2021
[FeFe] hydrogenase enzymes can reversibly catalyze the conversion of protons into molecular hydrogen. The active site of the [FeFe] hydrogenase enzyme is buried inside the protein.
