A multinuclear nuclear magnetic resonance study of the monovalent-divalent cation sites of pyruvate kinase.
The effectiveness of measuring distances between monovalent and divalent cation sites on enzymes has been examined by 6Li, 7Li, I4N, 15N, 23Na, 39K, 85Rb, 87Rb, and 133Cs nuclear magnetic resonance (NMR). Measurements were made of the paramagnetic effect of enzyme-bound Mn2+ on the longitudinal spin-lattice relaxation rate ( l /T l ) of the monovalent cations by using MnZ+ at the divalent catio...
متن کاملMonovalent and Divalent Cation Permeation
Single channel patch-clamp techniques were used to study nicotinic acetylcholine receptors in cultured rat myotubes. The single channel conductance in pure cesium and sodium levels off at high concentrations, as if a binding site within the channel were saturating . The conductances at very low concentrations, however, are larger than predicted by the simplest one-site transport model fitted to...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
متن کاملA Nano-Composite Based on Fe3O4@Styrene-Maleic Anhydride Copolymer as a Magnetic Sorbent for Preconcentration of Silver(I) Ion
A magnetic nano-composite based on modified styren-maleic anhydride copolymer and Fe3O4 nano-particles was introduced as a new sorbent for solid-phase extraction and preconcentration of trace levels of silver ion from aqueous solutions. The size and morphology of the nano-sorbent were characterized via X-ray diffraction analysis, scanning electron microscopy and Fourier transform infrared spect...
