Functional basis of electron transport within photosynthetic complex I [PDF]

, 2021
Photosynthesis and respiration rely upon a proton gradient to produce ATP. In photosynthesis, the Respiratory Complex I homologue, Photosynthetic Complex I (PS-CI) is proposed to couple ferredoxin oxidation and plastoquinone reduction to proton pumping ...

Age-related deficiencies in complex I endogenous substrate availability and reserve capacity of complex IV in cortical neuron electron transport

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2010
Respiratory enzyme complex dysfunction is mechanistically involved in mitochondrial failure leading to neurodegenerative disease, but the pathway is unclear. Here, age-related differences in mitochondrial respiration were measured in both whole and permeabilized neurons from 9-month and 24-month adult rat cortex cultured in common conditions.

Dissection of the asynchronous transport of intestinal microvillar hydrolases to the cell surface [PDF]

, 1988
Novel subcellular fractionation procedures and pulse-chase techniques were used to study the intracellular transport of the microvillar membrane hydrolases sucrase-isomaltase and dipeptidylpeptidase IV in the differentiated colon adenocarcinoma cell line

Tissue-specific mitochondrial HIGD1C promotes oxygen sensitivity in carotid body chemoreceptors

eLife, 2022
Mammalian carotid body arterial chemoreceptors function as an early warning system for hypoxia, triggering acute life-saving arousal and cardiorespiratory reflexes. To serve this role, carotid body glomus cells are highly sensitive to decreases in oxygen

Enhancing mitochondrial activity in neurons protects against neurodegeneration in a mouse model of multiple sclerosis

eLife, 2021
While transcripts of neuronal mitochondrial genes are strongly suppressed in central nervous system inflammation, it is unknown whether this results in mitochondrial dysfunction and whether an increase of mitochondrial function can rescue ...

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

, 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.

Glutathione binding to the plant AtAtm3 transporter and implications for the conformational coupling of ABC transporters

eLife, 2022
The ATP binding cassette (ABC) transporter of mitochondria (Atm) from Arabidopsis thaliana (AtAtm3) has been implicated in the maturation of cytosolic iron-sulfur proteins and heavy metal detoxification, plausibly by exporting glutathione derivatives ...

Sordaria macrospora Sterile Mutant pro34 Is Impaired in Respiratory Complex I Assembly

Journal of Fungi, 2022
The formation of fruiting bodies is a highly regulated process that requires the coordinated formation of different cell types. By analyzing developmental mutants, many developmental factors have already been identified.
