shown that a receptor-constrained three-dimensional screening program (DOCK) can be used to identify potential ligands (ergo substrates) for the enzyme (De Voss, J. J.; Sibbesen, O.; Zhang, Z.; Ortiz de Montellano, P. R. J. Am. Chem. Soc. 1997, 119, 5489). A new set of 10 compounds has now been examined to further test the substrate specificity of P450cam and the ability of DOCK to identify substrates for
细胞色素P450cam催化异种
生物的催化转换既导致有机代谢物的形成,又导致
H2O2和
H2O的产生不耦合。先前的研究表明,可以使用受受体约束的三维筛选程序(DOCK)来识别该酶的潜在
配体(ERGO底物)(De Voss,JJ; Sibbesen,O。; Zhang,Z。; Ortiz de Montellano ,PRJ Am.Chem.Soc.1997,119,5489)。现在已经检查了一组新的10种化合物,以进一步测试P450cam的底物特异性和DOCK识别该酶底物的能力。结果扩展了P450cam的已知特异性,并定义了使用DOCK预测其底物特异性的局限性。
