title: Effective blocking of HIV-1 proteinase activity by characteristic inhibitors of aspartic proteinases.
abstract: Inhibitory constants (Ki) between 5 and 35 nM were derived (under different conditions of pH and ionic strength) for the interaction of HIV-1 proteinase with acetyl-pepstatin and H-261, two characteristic inhibitors of aspartic proteinases. Thus this enzyme, essential for replication of the AIDS virus, may be classified unequivocally as belonging to this proteinase family.
