A biophysical model of the mitochondrial respiratory system and oxidative phosphorylation. [PDF]

PLoS Computational Biology, 2005
A computational model for the mitochondrial respiratory chain that appropriately balances mass, charge, and free energy transduction is introduced and analyzed based on a previously published set of data measured on isolated cardiac mitochondria.

Is impaired energy production a novel insight into the pathogenesis of pyridoxine-dependent epilepsy due to biallelic variants in ALDH7A1?

PLoS ONE, 2021
BackgroundPyridoxine-dependent epilepsy (PDE) is due to biallelic variants in ALDH7A1 (PDE-ALDH7A1). ALDH7A1 encodes α-aminoadipic semialdehyde dehydrogenase in lysine catabolism.

Mitochondrial morphology is associated with respiratory chain uncoupling in autism spectrum disorder

Translational Psychiatry, 2021
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is associated with unique changes in mitochondrial metabolism, including elevated respiration rates and morphological alterations.

A Structural Model of the Cytochrome c Reductase/Oxidase Supercomplex from Yeast Mitochondria [PDF]

, 2007
Mitochondrial respiratory chain complexes are arranged in supercomplexes within the inner membrane. Interaction of cytochrome c reductase (complex III) and cytochrome c oxidase (complex IV) was investigated in Saccharomyces cerevisiae. Projection maps at

Electron Transport Chain Complex II Regulates Steroid Metabolism

iScience, 2020
Summary: The first steroidogenic enzyme, cytochrome P450-side-chain-cleavage (SCC), requires electron transport chain (ETC) complexes III and IV to initiate steroid metabolic processes for mammalian survival.

Structure of a bacterial type IV secretion core complex at subnanometre resolution [PDF]

, 2013
Type IV secretion (T4S) systems are able to transport DNAs and/or proteins through the membranes of bacteria. They form large multiprotein complexes consisting of 12 proteins termed VirB1-11 and VirD4.

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

Pulmonary 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

Surface Fluorescence Studies of Tissue Mitochondrial Redox State in Isolated Perfused Rat Lungs [PDF]

, 2012
We designed a fiber-optic-based optoelectronic fluorometer to measure emitted fluorescence from the auto-fluorescent electron carriers NADH and FAD of the mitochondrial electron transport chain (ETC).
