Characterization of poly(ADP-ribose)polymerase from Crithidia fasciculata: Enzyme inhibition by β-lapachone

Crithidia fasciculata poly(ADP-ribose)polymerase (PARP) has been isolated and partially purified. This is the first PARP isolated from trypanosomatids; it requires DNA and histone for activity, using NAD+ as substrate. Thiol compounds specially dithiothreitol essentially contributed to PARP stabilit...
