WebMar 15, 2004 · First, cysteine protease inhibitors block the hydrolysis of hemoglobin by cultured parasites, causing the food vacuole to swell and fill with undegraded hemoglobin (11, 20–22). Second, cysteine protease inhibitors block the development of cultured P. falciparum parasites (11, 23) and cure mice infected with murine malaria parasites . The first step in the reaction mechanism by which cysteine proteases catalyze the hydrolysis of peptide bonds is deprotonation of a thiol in the enzyme's active site by an adjacent amino acid with a basic side chain, usually a histidine residue. The next step is nucleophilic attack by the deprotonated cysteine's anionic sulfur on the substrate carbonyl carbon. In this step, a fragment of the substrate is rel…

WebCPs’ catalytic mechanism involves hydrolysis of peptide bond performed by deprotonation of a thiol group present in the active site of the enzyme carried out by an adjacent residue having a basic side chain, usually a histidine. Deprotonation of a thiol group may start nucleophilic attack by deprotonated cysteine on its substrate ( Fig. 2.7 ).
