Clustering of polymorphic residues on the surface of AMA1. Side chains 197, 200, 230, and 243, shown in red, are highly polymorphic. High-frequency dimorphisms are shown in orange, with low-frequency dimorphisms in yellow, as described in Materials and Methods. (a) Surface view of the “nonpolymorphic face.” (b) Surface view of the “polymorphic face.” Areas colored violet are disordered in the structure.
