Dolastatin 10, a potent tubulin-targeting marine anticancer natural product, provided the basis for the development of six FDA-approved antibody–drug conjugates. Through the screening of cyanobacterial Caldora penicillata environmental DNA libraries and metagenome sequencing, we identified its biosynthetic gene cluster. Functional prediction of 10 enzymes encoded in the 39 kb cluster supports the dolastatin
Dolastatin 10 是一种有效的微管蛋白靶向海洋抗癌天然产物,为 FDA 批准的六种抗体药物偶联物的开发提供了基础。通过对蓝藻Caldora penicillata环境DNA文库的筛选和宏基因组测序,我们鉴定了其生物合成基因簇。 39 kb 簇中编码的 10 种酶的功能预测支持多拉司他汀 10 的生物合成。非血红素二铁单加氧酶 DolJ 的生化特征是介导多拉司他汀 10 中末端噻唑的形成。
