Figure 3.

Alignment of C-terminal p19 regions of merozoite surface protein 1 (MSP1). The deduced amino acid sequences encompassing the predicted MSP1-p19 C-terminal regions (underlined) of the indicated Plasmodium species (denoted by P. and the first 3 letters of the species name) were aligned. P. falA and P. falB refer to Plasmodium falciparum strains K1 and MAD20, respectively, and P. viv refers to the Plasmodium vivax Belem strain. Amino acid differences (lower case letters) vs. the Consensus sequence (upper case letters) are shown. Gaps introduced to maximize alignment (dashes), positions identical to the Consensus sequence (dots), and positions within the Consensus lacking a plurality (X) are indicated. Positions of conserved cysteine residues are shaded. The predicted GPI anchor site (arrow) and the conserved residues (box) surrounding it are indicated.
