Malaria parasites contain a complete glutathione (GSH) redox system, and several enzymes of this system are considered potential targets for antimalarial drugs. Through generation of a gamma-glutamylcysteine synthetase (gamma-GCS)-null mutant of the rodent parasite Plasmodium berghei, we previously showed that
