Figure 6. Structural features on PfRH5.
Structural features are outlined on the crystal structure of PfRH5 (αα K140–K247 + N297–Q526, yellow) bound to the two Ig domains of the basigin receptor (blue)40. The putative N-linked glycan is shown in red at position N214 with two N-acetyl glucosamines and nine mannose residues–the largest type of glycan found on the insect cell expressed proteins60. The other site which may be glycosylated, N38, is within the disordered N-terminal region of PfRH5 which is not shown in the structure. The buried cysteine at position C329 and the C203Y polymorphism are highlighted in pink.
