Cardiolipin-based respiratory complex activation in bacteria.
Anionic lipids play a variety of key roles in membrane function, including functional and structural effects on respiratory complexes. However, little is known about the molecular basis of these lipid-protein interactions. In this study, NarGHI, an anaerobic respiratory complex of Escherichia coli, has been used to investigate the relations in between membrane-bound proteins with phospholipids....
متن کاملCardiolipin requirement for electron transfer in complex I and III of the mitochondrial respiratory chain.
Almost complete phospholipid depletion has been achieved for Complex I and III of the mitochondrial respiratory chain using a technique that involves elution on Sephadex LH-20 in the presence of Triton X-100. Enzymic activity may be regenerated by replenishment with phospholipid. However, restoration of enzymic activity in phospholipid-depleted Complex I and III has been shown to require the pr...
متن کاملAn unusual phosphatidylethanolamine-utilizing cardiolipin synthase is discovered in bacteria.
C ardiolipin (also known as diphosphatidylglycerol) is a four-chained anionic membrane phospholipid composed of two phosphatidyl moieties joined by a glycerol link (Fig. 1). It was first isolated from beef heart as a serologically active phospholipid (1), hence the name cardiolipin. In animals, plants, and lower eukaryotic organisms (e.g., yeast), cardiolipin is a component of the inner mitocho...
متن کاملCardiolipin Supports Respiratory Enzymes in Plants in Different Ways
In eukaryotes the presence of the dimeric phospholipid cardiolipin (CL) is limited to the mitochondrial membranes. It resides predominantly in the inner membrane where it interacts with components of the mitochondrial electron transfer chain. CL deficiency has previously been shown to affect abundances of the plant NADH-dehydrogenase complex and its association with dimeric cyctochrome c reduct...
متن کاملTemperature Activation of Certain Respiratory Enzymes of Stenothermophilic Bacteria
The results of this study of the effect of temperature on the respiratory mechanism of five stenothermophilic bacteria may be summarized as follows:- 1. The respiratory mechanism and its various components of the stenothermophilic bacteria were found to function at temperatures below the minimum temperature for growth of these organisms. In every case the rates of the individual reactions invol...
