    New anti-malarial treatments are desperately required to face the spread of drug resistant parasites. Inhibition of metalloaminopeptidases, PfA-M1 and PfA-M17, is a validated therapeutic strategy for treatment of Plasmodium falciparum malaria. Here, we describe the crystal structures of PfA-M1 and PfA-M17 bound to chemotherapeutic agent Tosedostat. The inhibitor occupies the enzymes' putative product egress channels in addition to the substrate binding pockets; however, adopts different binding poses when bound to PfA-M1 and PfA-M17. These findings will be valuable for the continued development of selective inhibitors of PfA-M1 and PfA-M17.
