Highly sensitive: The azido analogue of methionine, azidohomoalanine (see picture), is shown to be a sensitive IR probe of protein structure, folding, and electrostatics, as demonstrated for ribosomal protein NTL9. It can be readily incorporated in to proteins, and the azido frequency is significantly blue‐shifted in the thermally unfolded state.
高度敏感:甲硫氨酸的叠氮基类似物叠氮高丙氨酸(见图片)被证明是蛋白质结构、折叠和静电的敏感 IR 探针,如核糖体蛋白 NTL9 所证明的那样。它可以很容易地结合到蛋白质中,并且叠氮频率在热展开状态下显着蓝移。
