An NAD:cysteine ADP-ribosyltransferase designated ADP-ribosyltransferase C was purified approximately 35,000-fold from human erythrocytes with an 11% yield. The purified ADP-ribosyltransferase C exhibited one predominant protein band on sodium dodecyl sulfate-polyacrylamide gels with an estimated molecular weight (Mr) of 28,500. The

Nine low-Mr thiols were compared with regard to their ability to function as myeloperoxidase-oxidase substrates under conditions where no auto-oxidation of the thiols could be observed. The methyl and ethyl esters of cysteine were found to be about twice as

Trihaloacetaldehydes are used as sedatives, are key intermediates in the metabolism of 1,1,1,2-tetrahaloethanes, some of which are chlorofluorocarbon substitutes, and are metabolites of trihaloethanols, which are intestinal and bone marrow toxins. In the present study, trifluoroacetaldehyde was used as a

Several disulfide-reducing agents, such as dithiothreitol, 2,3-dimercapto-1-propanol, cysteine ethyl ester, and cysteine methyl ester enhanced the effectiveness of 1-methyladenine (1-MeAde) to induce oocyte maturation in the starfish Asterina pectinifera. This enhancement occurred at relatively low concentrations at which these agents
