Abstract A purified Plasmodium falciparum serine protease (gp76) implicated in erythrocyte invasion, degrades human erythrocyte band 3 and glycophorin A. Inhibition studies using synthetic peptides derived from the presumed band 3 enzymatic cleavage sites and the observed uptake of fluorescent phospholipids following gp76 treatment, suggest that band 3 degradation by this serine protease participates in the formation of the parasitophorous vacuole by restructuring the red cell cytoskeleton. These results provide a rationale for the elaboration of specific inhibitors to block red cell invasion by malaria parasites.
