Ca-translocating ATPase of the plant plasma membrane.
For Ca(2+) to function as a second messenger in signal transduction, it is essential that plant cells maintain low cytoplasmic Ca(2+) levels relative to internal organelles and the apoplast. At the plasma membrane, Ca(2+) is actively transported out of the cytoplasm and current evidence supports the involvement of a primary Ca(2+)-translocating ATPase in mediating this energy-dependent process....
متن کاملThermal analysis of the plasma membrane Ca- ATPase
The plasma membrane Ca-ATPase is a well known enzyme in eucaryotes able to extrude calcium to the extracellular space in order to restore intracellular calcium to very low levels. This ATPase needs plasma membrane lipids such as acidic phospholipids in order to maintain its activity. In this study, we investigated the role that calcium and cholesterol play on the thermal stability of the Ca-ATP...

متن کامل-ATPase of Erythrocyte Plasma Membrane
The regulation of Ca in human body is performed by Ca-ATPase. The affinity of erythrocyte plasma membrane Ca-ATPase (PMCA) was examined for three different porphyrin compounds, Tetraphenylporphinesulfonate (TPPS), 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron(III) Chloride (FeTPPS) and 5,10,15,20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron(III) nitrosyl Chloride (FeNOTPPS), by en...
متن کاملA transgene encoding a plasma membrane H+-ATPase that confers acid resistance in Arabidopsis thaliana seedlings.
Proton pumps (H+-ATPases) are the primary active transport systems in the plasma membrane of higher plant cells. These enzymes are encoded by a large gene family expressed throughout the plant, with specific isoforms directed to various specialized cells. While their involvement in membrane energetics has been suggested by a large body of biochemical and physiological studies, a genetic analysi...
