中文摘要
从山竹藤黄(Garcinia mangostana L.)中分离到新型III型PKS,主要含有烯丙基化的山酮类化合物。鉴定了一种关键的戊烯基转移酶,该酶参与真菌从3,5-二甲基丁香酸衍生的丰富的美罗萜类化合物的生物合成。该戊烯基化产物是真菌中一系列巯基萜类化合物生物合成的关键中间体。利用我们的工程菌株酿酒酵母(Saccharomyces cerevisiae, SCKW5),以尼德兰曲霉(Aspergillus nidlans)为原料,开发了酵母代谢工程,用于异源生产tryprostatins和其他化合物。进一步构建以毛藻为原料形成次生代谢物的综合体系的试验正在进行中。
英文摘要
Novel type III PKS was isolated from Garcinia mangostana L. , which contains mainly prenylated xanthones. A key prenyltransferase involved in the biosynthesis of abundant fungal meroterpenoids derived from 3,5-dimethylorsellinic was identified. The prenylated product serves as a key intermediate in the biosynthesis of series of meroterpenoids in fungi. With Aspergillus nidlans, Metabolic engineering of yeast for heterologous production of tryprostatins and other compounds was developed through our engineered strain of Saccharomyces cerevisiae, SCKW5. Further trial to architect comprehensive system to form secondary metabolites with Chaetomium globosum is under progress.
