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

5'-Nucleotidase of bull seminal plasma has been spin labeled with the sulfhydryl reagent 3-maleimidoproxyl. ESR analysis reveals the presence of two classes of labeled sites. The first is characterized by a long spin label rotational correlation time, from which a

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

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

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
