A new spin-label method for the measurement of the internal microviscosity of erythrocyte is presented. The spin label used is 2,2',5,5'-tetramethyl-3-maleimidopyrrolidinyl-N-oxyl (MAL-5) which penetrates inside the red blood cell and binds covalently on cytoplasmic glutathione. After washing off the external

A spin-labeled derivative of the ion channel peptide cecropin AD (Fink et al., 1988) was synthesized and used to investigate its aggregation state in water and in the presence of a helix-promoting solvent. A cysteine was introduced at position 33

We have used electron paramagnetic resonance (EPR) to investigate the orientation, rotational motion, and actin-binding properties of rabbit psoas muscle cross-bridges in the presence of the nonhydrolyzable nucleotide analogue, 5'-adenylylimido-diphosphate (AMPPNP). This analogue is known to decrease muscle tension without

The 16-kDa proteolipid from the hepatopancreas of Nephrops norvegicus belongs to the class of channel proteins that includes the proton-translocation subunit of the vacuolar ATPases. The membranous 16-kDa protein from Nephrops was covalently spin-labeled on the unique cysteine Cys54, with

EPR titration of tubulin with an allocolchicine spin probe showed more than one binding site: one high-affinity binding site (Kd = 8 microM), consistent with the Ki found for competition with colchicine, and one or more low-affinity site(s) (Kd higher
