Plasmodium KAHRP orthologs and structural similarities of exported proteins. (a) Structural alignment of P. falciparum KAHRP and orthologs from P. fragile and P. vivax. Note that PfrKAHRP and PvKAHRP-c represent incomplete sequences (amino terminus represented as dashed line). (b) Structural representation of P. falciparum exported protein families. Secondary structure prediction was performed using the consensus method Jnet [84,85].
