Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]
, 1992 Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...

mPTP opening differently affects electron transport chain and oxidative phosphorylation at succinate and NAD-dependent substrates oxidation in permeabilized rat hepatocytes [PDF]
The Ukrainian Biochemical Journal, 2020 Mitochondrial Ca2+ overload may trigger the opening of mitochondrial permeability transition pore (mPTP) and its prolonged activation leads to cell death. ATP synthase is considered as a possible molecular component of the pore. The aim of this study was
