开发了一种重组细胞色素P450cam的结晶方法,避免了先前报道的玻璃毛细管自由界面扩散法固有的困难。表面突变Cys334- >Ala (C334A),最初设计用于防止二聚体的形成,从而改善酶的常规处理,通过悬垂气相扩散技术促进结晶。(C334A)P450cam晶体在48小时内生长,并在西门子多线区域探测器内部100 K下衍射到1.2 A以上。数据已从樟脑绑定表收集到1.35 A。
A procedure for the crystallization of recombinant cytochrome P450cam has been developed which avoids the difficulties inherent in the glass-capillary free-interface diffusion method reported previously. The surface mutation, Cys334-->Ala (C334A), originally designed to prevent dimer formation and thus improve routine handling of the enzyme, facilitates crystallization by the hanging-drop vapour-diffusion technique. Crystals of (C334A)P450cam grow within 48 h and diffract to beyond 1.2 A at 100 K in-house on a Siemens multiwire area detector. Data have been collected from the camphor-bound form to 1.35 A.
