We have developed two methods for quantitatively measuring inorganic pyrophosphate (PPi) in the presence of 10(3)--10(4) molar excesses of inorganic phosphate (Pi) and used them to measure the extent ...
Inorganic constituents of the leaves of several kinds of plants growing on different soil types were investigated using energy-dispersive X-ray fluorescence spectrometry. The results can be summarized...
Four different techniques, equilibrium dialysis, protection of enzymatic activity against chemical inactivation, 31P relaxation rats, and water proton relaxation rates, are used to study divalent meta...
Inorganic phosphate (Pi) uptake by Catharanthus roseus (L.) G. Don cells was studied in relation to its apparent uncontrolled uptake using 31P-nuclear magnetic resonance spectroscopy. Kinetics of Pi u...
The interaction of inorganic pyrophosphatase from E. coli with inorganic phosphate (Pi) was studied in a wide concentration range of phosphate. The apoenzyme gives two inactive compounds with Pi, a pr...
1. Whole scrapings of rat intestinal mucosa were incubated with carrier-free sodium [(35)S]sulphate. Radioactivity was found in S-sulphocysteine and to a small extent in S-sulphoglutathione. 2. Whole ...
