Ro, Dae-Kyun et al. "Production of the Antimalarial Drug Precursor Artemisinic Acid in Engineered Yeast." Nature. 2006.
This paper describes the engineering of a strain of yeast to produce artemisinic acid, a precursor to the anti-malarial agent artemisinin produced by the plant Artemisia annua. Through engineering its mevalonate pathway, the yeast was able to produce high amounts of isoprenoid precursor. The artemisinic acid biosynthetic genes were expressed in the engineered yeast strain, including a cytochrome P450 gene which was identified de novo. This unusual cytochrome P450 catalyzes three successive oxidations of the substrate. Up to 100 mg of artemisinic acid per 1 culture were produced by this strain.

Martin, VJ et al. "Engineering a Mevalonate Pathway in Escherichia coli for Production of Terpenoids." Nature Biotechnology. 2003.
In this report, researchers from the Keasling lab describe how they engineered E. coli to produce high amounts of isoprenoid precursors by expressing the mevalonate pathway from yeast. The E. coli cells were also engineered to express the amorphadiene synthase gene from Artemisia annua. Amorphadiene, a precursor to artemisinin, was produced at about 24 micrograms per liter of culture.

This document presents a broad discussion of malaria as well as official WHO recommendations for its control and treatment. It covers topics of disease burden, disease management, prevention, epidemic control, special cases such as pregnant women and children, monitoring and evaluation, capacity development, and community mobilization.
