Abstract

An (X-ray) eye for detail: Modern high-resolution protein crystallography allows H atoms to be located. Applied to nickel-iron hydrogenase, X-ray structural analysis has finally confirmed the presence of an active-site hydride and thiol, as well as unveiling the intricate pathways that protons take to and from the active site.

摘要

洞察细节的(X射线)慧眼:现代高分辨率蛋白质晶体学能够确定氢原子的位置。将其应用于镍铁氢化酶,X射线结构分析最终证实了活性位点处存在氢化物和硫醇,同时也揭示了质子进出活性位点的复杂路径。
