Fig. 1From: Genetic diversity of Plasmodium vivax metacaspase 1 and Plasmodium vivax multi-drug resistance 1 genes of field isolates from Mauritania, Sudan and OmanAlignment histidine and cysteine residues in the catalytic domain of metacaspases. The universally conserved histidine (His) and cysteine (Cys) residues are marked by a star in the catalytic site. In the PfMCA1 catalytic site, His–Cys are found at position 404 and 460. In the PvMCA1-cd, His–Cys, were identified at position 372 and 428, as well as in P. vivax from Mauritania, Brazil, India and North Korea. A second potential putative catalytic site His–Cys was also identified upstream of the catalytic domain at positions 282-305 in the five P. vivax sequences. Accessions of reference strains are PF13-0289 (ABC84559), PVX-114725 (EDL46606), PVMG-03834 (KMZ92479), PVBG-03488 (KMZ86023), PVIIG-01002 (KMZ79728), PVNG-00719 (KMZ98925)Back to article page
