title: Peptidases from Plasmodium falciparum cultured in vitro.
abstract: An acid peptidase that degrades hemoglobin optimally at pH 3.5, a neutral aminopeptidase and an alkaline endopeptidase that acts on an alpha-N-blocked synthetic substrate have been demonstrated in Plasmodium falciparum in culture. The enzymes were shown to be distinct by anion exchange chromatography, gel filtration on Sephadex G-200 and isoelectric focusing. The activities of the acid peptidase and the aminopeptidase were inhibited by antimalarial compounds.
