The decay of the pH difference (DeltapH) across soybean phospholipid vesicular membrane by ionophore A23187 (CAL)-mediated H+/M+ exchange (M+ = Li+, Na+, K+, and Cs+) has been studied in the pH range 6-7.6. The DeltapH in these experiments were creat

The hypothesis that a dominant barrier to the translocation of organic ions (such as carbonyl cyanide m-chlorophenylhydrazone (CCCP)) across phospholipid bilayer membranes is located between the “polar region” and “nonpolar region” of the mem

By appropriate instrumentation, saturation recovery in electron spin resonance has been observed with pulsed observing microwave power. The observing power was ∼100% amplitude modulated with a low duty cycle, in order to sample the magnetization pe

The X-band EPR spectra of Cu(cal) 2 complex in CHCl 3 solutions (cal = calcimycin) do not show resolved 14 N hyperfine structure (J. S. Puskin and T. E. Gunter, Biochemistry 14 , 187, 1975) even though they are expected from the nitrogen coordination

Two copper(II) complexes in equilibrium contribute to the solution EMR (EPR) spectrum of bis(ethylacetoacetato)copper(II). In the present paper, EMR line-widths have been analysed to obtain better insight into the nature of these two paramagnetic spe

Theoretical expression for the rate of decay of delta pH across vesicular membrane due to carrier-mediated ion transports, 1/tau, has been modified taking note of carrier states (such as mon- and mon-H-M+) for which the translocation rate constants i

The decay of delta pH across vesicular membranes by nigericin-mediated H+ and metal ion (M+) transports has been studied at 25 degrees C after creating delta pH by temperature jump (T-jump). In these experiments K+ or Na+ were chosen as M+ for the co

The “minimum linewidths” seen in the ESR linewidths against temperature plots, the dependence of line widths on the63Cu nuclear magnetic quantum numbers and the Hubbard relation provide sufficient number of equations to determine the anisotropic

Two rate-limiting mechanisms have been proposed to explain the gramicidin channel facilitated decay of the pH difference across vesicular membrane (delta pH) in the pH region 6–8 and salt (MCI, M+ = K+, Na+) concentration range 50–300 mM. 1) At l

The forward rate constant for the binding of Bromophenol blue to lysozyme is estimated to be 10 5 M −1 · s −1 at room temperature and ionic strength 0.01, from the line broadening of the 1 H-NMR spectrum of Bromophenol blue at 270 MHz. The broad
