Oligo-arginines are cell-penetrating peptides and find use as carriers for transportation of various membrane-impermeable biopharmaceuticals into target cells. We have found that oligo-arginines of a length of 4-10 amino acids, but especially (Arg)(8), are able to inhibit the major intracellular proteolytic system, the proteasome, with mixed-type inhibition(More)
A nonradioactive spectrometric assay for the evaluation of inhibitors of phosphatidylinositol-specific phospholipase C (PI-PLC) is described. l-alpha-Phosphatidylinositol from bovine liver was used as substrate in the presence of the micelle-forming detergent deoxycholic acid. PI-PLC isolated from Bacillus cereus and crude cytosol fractions from porcine(More)
