NDUFA4 Is a Subunit of Complex IV of the Mammalian Electron Transport Chain [PDF]
The oxidative phosphorylation system is one of the best-characterized metabolic pathways. In mammals, the protein components and X-ray structures are defined for all complexes except complex I. Here, we show that NDUFA4, formerly considered a constituent of NADH Dehydrogenase (CI), is instead a component of the cytochrome c oxidase (CIV).

Mitochondrial Function and Parkinson’s Disease: From the Perspective of the Electron Transport Chain
Parkinson’s disease (PD) is known as a mitochondrial disease. Some even regarded it specifically as a disorder of the complex I of the electron transport chain (ETC).

Inhibitory Effect of ATP on Cytochrome c Oxidase Depends on Electron Entry Pathways by TCA Cycle Metabolites [PDF]
The ATP-dependent inhibition of cytochrome c oxidase (CytOx, complex IV of the electron transport chain) is the second mechanism of respiratory control adjusting mitochondrial respiration in order to prevent excessive electron flow and reactive oxygen ...

Complex I preserves mitochondrial polarization during infection of human macrophages by secretion-competent bacteria [PDF]
Intracellular bacteria remodel host bioenergetics and modulate mitochondrial membrane potential (Δψm). However, how individual electron transport chain (ETC) components sustain Δψm during infection of primary human macrophages remains unclear.

Impact of mitochondrial reductive stress due to respiratory chain limitation on cancer via posttranslational modifications [PDF]
Respiratory chain limitation is a recurrent but spatially heterogeneous state in solid tumors, driven by hypoxic subregions, electron transport chain defects, and signaling- or therapy-imposed respiratory inhibition.

Direct dapagliflozin exposure enhances respiration and membrane hyperpolarization in isolated cardiac mitochondria [PDF]
Dapagliflozin, a sodium–glucose cotransporter 2 (SGLT2) inhibitor widely used for the treatment of diabetes, has been consistently associated with cardiovascular protection, including attenuation of ischemia/reperfusion injury and reduced incidence of ...

New insight into the mechanism of mitochondrial cytochrome c function. [PDF]
We investigate functional role of the P76GTKMIFA83 fragment of the primary structure of cytochrome c. Based on the data obtained by the analysis of informational structure (ANIS), we propose a model of functioning of cytochrome c. According to this model,

ETMB-RBF: discrimination of metal-binding sites in electron transporters based on RBF networks with PSSM profiles and significant amino acid pairs. [PDF]
BACKGROUND: Cellular respiration is the process by which cells obtain energy from glucose and is a very important biological process in living cell. As cells do cellular respiration, they need a pathway to store and transport electrons, the electron ...
