α-裂解酶的正常功能需要它的存在 N-末端的PRO区域,它催化了一个尚未确定的步骤 这种酶的折叠。为了更好地理解折叠 机制,我们正在使用X射线结晶学来确定 亲区域的结构,既有自身的,也有复杂的 折叠蛋白水解酶。我们已经设计了几个突变体,其中包括 半胱氨酸促进重原子衍生物的制备 多个同构替换。
英文摘要
Proper function of a-lytic protease requires the presence of its N-terminal pro region, which catalyzes an as yet unidentified step in the folding of this enzyme. In order to better understand the folding mechanism, we are using x-ray crystallography to determine the structure of the pro region, both by itself and in a complex with folded protease. We have engineered several mutants containing cysteines to facilitate the preparation of heavy atom derivatives for multiple isomorphous replacement.
