IspH is a 4Fe-4S protein that carries out an essential reduction step in isoprenoid biosynthesis. Using hyperfine sublevel correlation (HYSCORE) spectroscopy, we show that pyridine inhibitors of IspH directly bind to the unique fourth Fe in the 4Fe-4S cluster, opening up new routes to inhibitor design, of interest in the context of both anti-bacterial as well as anti-malarial drug discovery.
IspH 是一种 4Fe-4S 蛋白,在异戊烯基生物合成中执行一个必需的还原步骤。我们利用超精细亚层相关(HYSCORE)光谱学表明,IspH 的吡啶抑制剂直接结合到 4Fe-4S 簇中的独特的第四个铁原子上,为抑制剂设计开辟了新的途径,这在抗细菌和抗疟疾药物发现方面都具有重要意义。
