modelling and synthetic studies have been carried out on tyrosinyl adenylate and analogues to probe the interactions seen in the active site of the X-ray crystal structure of tyrosyl tRNA synthetase from Bacillus stearothermophilus, and to search for new inhibitors of this enzyme. Micromolar and sub-micromolar inhibitors of tyrosyl tRNA synthetases from both B. stearothermophilus and Staphylococcus aureus have
已经对酪氨酰腺苷酸及其类似物进行了分子建模和合成研究,以探测在嗜热脂肪芽孢杆菌的酪氨酰tRNA合成酶的X射线晶体结构的活性位点中观察到的相互作用,并寻找该酶的新抑制剂。已经合成了来自嗜热脂肪芽孢杆菌和金黄色葡萄球菌的酪氨酰tRNA合成酶的微摩尔和亚微摩尔抑制剂。腺嘌呤环对酪氨酸腺苷酸与酶结合的重要性以及水介导的氢键相互作用的重要性已得到强调。通过与金黄色葡萄球菌酶的同源性建模以及配体对接研究进一步支持了抑制数据。
