筛选在疟原虫中抑制GPI生物合成的化合物的方法
摘要：
本发明人成功地分离出了GWT1(PfGWT1)，其是一种在恶性疟原虫中参与GPI生物合成的酶。此外，本发明人揭示比编码PfGWT1蛋白的DNA具有更低AT含量的简并突变体DNA，能补偿GWT1－缺陷型酵母的表型。在此发现的基础上，本发明提供了疟原虫的GWT1蛋白，以及该蛋白在筛选抗疟药物的方法中的用途。本发明还提供了编码参有GPI生物合成的蛋白的简并突变体DNA，该DNA比天然DNA具有更低的AT含量。本发明还提供了利用该简并突变体DNA筛选抗疟药物的方法。
摘要（英）：

The present inventors succeeded in isolating GWT1 (PfGWT1), which is one of the enzymes involved in GPI biosynthesis in the malaria parasite P. falciparum. In addition, the inventors revealed that degenerate mutant DNAs, with a lower AT content than the DNA encoding the PfGWT1 protein, can complement the phenotype of GWT1-deficient yeast. Based on the findings, the present invention provides the GWT1 protein of malaria parasites and the use of the protein in methods of screening for antimalarial drugs. The present invention also provides degenerate mutant DNAs encoding proteins involved in GPI biosynthesis, and which have a lower AT content than the original DNAs. The present invention also provides methods of screening for antimalarial drugs which use the degenerate mutant DNAs.
