Pi synthase
WebJul 1, 2008 · This chapter is concerned with PIP-kinases, the enzymes producing PTDIns-bisphosphates with regulatory function, such as the well-characterized PtdIns (4,5)P2 or the less-well understood Ptd Ins (3,4)P1 and Ptdins ( 3,5), as well as new techniques for lipid analysis and new tools for the visualization of specific lipids. 4

WebNote: \text {P}_i Pi just stands for an inorganic phosphate group \text { (PO}_4^ {3-}\text) (PO43−). Like most chemical reactions, the hydrolysis of ATP to ADP is reversible. The reverse reaction, which regenerates ATP from ADP and \text P_i Pi, requires energy. PI has a polar and non-polar region, making the lipid an amphiphile. Phosphatidylinositol is classified as a glycerophospholipid that contains a glycerol backbone, two non-polar fatty acid tails, a phosphate group substituted with an inositol polar head group. The most common fatty acids of phosphoinositides are stearic acid in the SN1 position and arachidonic acid, in the SN2 position. Hydrolysis of phosphoinositides yield one mole of glycerol…
WebFeb 7, 2024 · Synthesis of phosphatidylinositol (PI) at the ER and of cardiolipin (CL) in mitochondria. PA, in the ER, is converted to CDP-DAG via the CDS enzymes. CDP-DAG is used by PIS, to synthesize PI. PA can be transferred from the ER to mitochondria, where it is transported across the OMM and IMS to the IMM. WebSo basically in mitochondria one pair of H+ produces 1 ATP. In other words due to movement of 2 protons across the membrane of mitochondria ; conformational change in …
