Abstract

We discuss our recently reported femtosecond (fs) X-ray emission spectroscopy results on the ligand dissociation and recombination in nitrosylmyoglobin (MbNO) in the context of previous studies on ferrous haem proteins. We also present a preliminary account of femtosecond X-ray absorption studies on MbNO, pointing to the presence of more than one species formed upon photolysis.

摘要

我们讨论了最近报道的关于亚硝酰基肌红蛋白（MbNO）中配体离解和重组的飞秒（fs）X 射线发射光谱结果，并结合先前对亚铁血红素蛋白的研究进行了讨论。我们还初步介绍了 MbNO 的飞秒 X 射线吸收研究，指出光解后形成了不止一种物种。
