Native sodium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

Native solium and potassium adenosine triphosphatase from guinea pig kidney accepted a phosphate group from radioactive inorganic phosphate to form an acyl phosphate bond at the active site in the presence or absence of sodium ion. Magnesium ion was always required. In the presence of sodium ion and absence of adenosine triphosphate, there was no phosphorylation by inorganic phosphate. Addition...

Potassium depletion in rats augments the specific renal lesions of phosphate loading. Since it has been shown that phosphate loading increases the specific cardiac lesions of potassium deficiency (12), it is concluded that the similar types of electrolyte imbalance (potassium depletion-phosphate load) act conversely in the two organs.

Thiobacillus thiooxidans cells became more hydrophobic but less adhesive to elemental sulfur in the presence of increasing potassium phosphate concentrations. At a fixed concentration of potassium phosphate, however, there was a peak of both cell hydrophobicity and adhesion to sulfur at around pH 5. Oxidation of sulfur by the cells was affected in a complex manner by the phosphate concentration...

the current study was conducted in order to evaluate the effect of mono and di-potassium phosphate combination (mdkp) on some quantitative and qualitative characteristics of iranian pomegranate (cv. malas-e-saveh) in pomegranate research center of saveh city, in 2012. to adjust the ph of the solution, the mono potassium phosphate and di-potassium phosphate combined with each other in the ratio ...

While studying the factors affecting the absorption of mineral elements by plants, the writer showed that the hydrogen-ion concentration of the medium affects the absorption of potassium and phosphorus by wheat seedlings grown in water cultures. (4) ^ More phosphorus was absorbed from potassium phosphate solutions with initial pH values of 5.0 and below than from those with pH values of 6.0 and...

The effects of valinomycin and nigericin on sugar chemotaxis in Spirochaeta aurantia were investigated by using a quantitative capillary assay, and the fluorescent cation, 3,3'-dipropyl-2,2'-thiodicarbocyanine iodide was used as a probe to study effects of chemoattractants on membrane potential. Addition of a chemoattractant, D-xylose, to cells in either potassium or sodium phosphate buffer res...

introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...
