Sammanfattning : The aim of the present study was to investigate the biosynthesis of the ATP synthase in various tissues, and to test hypotheses about possible models of activation of several mitochondrial proteins, the ATP/ADP translocase and UCPs, that could utilize the proton gradient, thus bypassing the ATP synthase. We have examined the role of the expression of the P1 isoform of the c-Fo subunit in the biogenesis of ATP synthase in brown adipose tissue. LÄS MER
Sammanfattning : Glucose metabolism in pancreatic α- and β-cells is believed to regulate secretion of glucagon and insulin, respectively. In β-cells, ATP links glucose metabolism to electrical activity and insulin secretion. LÄS MER
3. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP
Sammanfattning : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. LÄS MER
Sammanfattning : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. LÄS MER
Sammanfattning : Several high resolution electrophysiological techniques such as measurements of cell membrane capacitance and amperometry are used to detect exocytotic events. A novel method was developed in this study based on the expression of P2X2 receptor channel in secreting cells. LÄS MER
