3D electron diffraction reveals the chiral nature of the malaria pigment crystal hemozoin

Detoxification of heme in Plasmodium depends on its crystallization into hemozoin. This pathway is a major target of antimalarial drugs. X-ray powder diffraction has established that the unit cell contains a cyclic hematin dimer, yet the pro-chiral nature of heme supports formation of four distinct stereoisomers, two centrosymmetric and two...
