study, we developed a FRET-based assay system to estimate the kinetics of the stimulus-induced processing (peptide bond cleavage) reaction. Based on the FRET system, it was clarified that introduction of a sterically less-hindered or polar residue at the position adjacent to the stimulus-responsive amino acid accelerates the processing reaction.
在化学生物学领域中,通过刺激来控制肽基功能的方法引起了越来越多的关注。最近,我们报道了一种刺激反应性肽,暴露于刺激后可以裂解。在这项研究中,我们开发了一种基于FRET的测定系统,以评估刺激诱导的加工(肽键裂解)反应的动力学。基于FRET系统,澄清了在与刺激响应性氨基酸相邻的位置处引入空间较少受阻或极性的残基加速了加工反应。
