Effects of solubilizing agents before and after reacting the spin label with the ghosts indicate that at least three membrane sulfhydryl sites can be spin labeled. Druginduced changes in electron spin resonance spectra from the spin-labeled membranes suggest that the drugs alter the protein structure of one of the spin-labeled sites. © 1970, by The Williams & Wilkins Company
