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

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

A maleimide spin label strongly inhibits the phosphate/H+ symporter of rat liver mitochondria. While inducing half-maximal inhibition of transport, the spin label reacts preferentially with the SH groups of the carrier, which are at least of two types. One type
