X-ray absorption and EPR spectroscopy have been used to probe the copper site structure in galactose oxidase at pH 4.5 and 7.0. the results suggest that there are no major differences in the structure of the tetragonal Cu(II) site at these pH values.

Homogeneous soft tissue, as regards its magnetic relaxation properties, is well-modeled by solutions of cross-linked protein (see Koenig and Brown, Prog. NMR Spectr. 22, 487 (1991)). Interactions at the solute-solvent interface alter the hydrodynamic

The magnetic field dependence (dispersion profile) of 1/ T 1 of solvent water protons of solutions of the mammalian eye lens protein α-crystallin has a reversible nonlinear dependence on concentration which, as protein concentration increases above

We report results for proton 1/T1, 1/T2, and K, the rate of magnetization transfer from solvent to solute, for 5 and 10 wt. % solutions of bovine serum albumin, both native and chemically cross-linked, in undeuterated and approximately 50% deuterated

We argue that, for solutions of immobilized protein and for tissue, the dependence of 1 / T1 of solvent protons on B0 at low fields and 1 / T1p on B1 for all B0 are both manifestations of the same underlying phenomena: magnetization transfer between

The 1/T1 NMRD profiles of lipid vesicles with the paramagnetic ion Gd attached via a chelate covalently linked to the membrane surface show a peak at approximately 20 MHz indicating that fluctuations of approximately 10(-8) s contribute to the form o

The diffusive permeability to water molecules, Pd, of lipid vesicles with entrapped paramagnetic solute ions can be determined rapidly from analysis of the magnetic field dependence (nuclear magnetic relaxation dispersion, or NMRD profile) of T1 of e
