-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 کاملKinetic attributes of Na+, K+ ATPase and lipid/phospholipid profiles of rat and human erythrocyte membrane.
Kinetic properties of Na+, K+ ATPase of membranes from rat and human erythrocytes were examined. The enzyme stability decreased with incubation time. The Vmax of the human enzyme was about 4 times lower than the values of the rat enzyme. However the energies of activation were higher. Phase transition temperature for the rat and the human enzyme was 24 degrees C and 17 degrees C, respectively. ...
متن کاملLetter to the editor: "Role of the human erythrocyte in generation and storage of asymmetric dimethylarginine".
Proteolytic activity in whole blood may lead to release of the endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine (ADMA). We investigated the role of the human erythrocyte in storage and generation of ADMA in healthy controls (n = 36) and critically ill patients (n = 38). Both free and total (sum of free and protein-incorporated) ADMA were measured. Upon incubation of intact...
متن کاملActivation of human erythrocyte Ca2+-dependent Mg2+-activated ATPase by calmodulin and calcium: quantitative analysis.
The effect of Ca2+ and calmodulin on (CaM) on the activation of Ca2+-dependent Mg2+-activated ATPase (Ca2+,Mg2+-ATPase; ATP phosphohydrolase, EC 3.6.1.3) has been carried out because of the finding that the CaM dependence of the activation varies with the concentration of free Ca2+, similarly to brain phosphodiesterase and adenylate cyclase. The study was carried out in the absence of chelating...
متن کاملErythrocyte ghost Na+,K+-ATPase and blood pressure.
To examine the relationship between body mass index, blood pressure, and the Na+,K+-adenosine triphosphatase (ATPase) system, we measured the erythrocyte ghost Na+,K+-ATPase and the erythrocyte Na+ concentration in 120 blacks and 127 whites (136 males and 111 females). Blacks showed a 13.9% higher erythrocyte Na+ (7.63 +/- 0.19 vs 6.70 +/- 0.11 [SEM] mEq/L; p = 0.0001) and a 16.1% lower erythro...
