We have used time-resolved electron paramagnetic resonance (EPR) and quenched-flow kinetics in order to investigate the dynamics of Ca-ATPase conformational changes involved in Ca2+ pumping in sarcoplasmic reticulum (SR) membranes at 2 degrees C. The Ca-ATPase was selectively labeled with

The determination of the iodoacetamide spin label orientation in myosin heads (Fajer, 1994) allows us for the first time to determine directly protein orientation from EPR spectra. Computational simulations have been used to determine the sensitivity of EPR to both

The labeling kinetics of sarcoplasmic reticulum ATPase with the iodoacetamide spin probe N-(1-oxy-2,2,6,6-tetramethyl-4-piperidinyl)iodoacetamide were followed under conditions designed to selectively label all reactive groups. Approximately 1 mol of spin-label reacted per one 100 000-dalton ATPase chain, indicating only one residue

Alterations in erythrocyte membranes caused by UICC B chrysotile asbestos fibres were studied in red cell ghosts using the spin label technique. The electron paramagnetic resonance (EPR) spectra of two sulphydryl reactive spin labels and one fatty acid spin probe

Sarcoplasmic reticulum vesicles were labeled with [14C]iodoacetamide spin-label (ISL) under conditions where time courses of the reaction predicted that one amino acid residue would be preferentially labeled. Solubilized tryptic peptides were separated by high-performance liquid chromatography following extensive digestion, and
