氢-氘交换(HDX)是一种测量蛋白质氢与含D2 O缓冲液中氘的交换的技术,提供结构动力学的读数。组氨酸氢-氘交换质谱(His-HDX-MS)是该技术的一种变体,可测量组氨酸咪唑C2氢的慢HDX。当伴随pH滴定时,该测量可提供蛋白质中单个组氨酸残基的HDX反应的pKa和半衰期(t1/2)。pKaandt 1/2值分别表示组氨酸残基的静电环境和侧链溶剂可及性程度。在这里,我们描述了一个实验方案,以表征视紫红质的His-HDX-MS。这种技术可以用来监测不同状态的视紫红质,并可能是有用的监测长期规模的事件,在其他GPCR。
Hydrogen–deuterium exchange (HDX) is a technique that measures the exchange of protein hydrogens for deuteriums in a D2O-containing buffer, providing readout of the structural dynamics. Histidine hydrogen–deuterium exchange mass spectrometry (His-HDX-MS) is a variation of this technique that measures the slow HDX of imidazole C2hydrogens of histidines. This measurement, when accompanied by pH titration, provides both pKas and half-lives (t1/2) of the HDX reaction for individual histidine residues in proteins. The pKaandt1/2values indicate the electrostatic environment and the degree of side-chain solvent accessibility of the histidine residues, respectively. Herein we describe an experimental protocol to characterize rhodopsin by His-HDX-MS. This technique can be used to monitor different states of rhodopsin and might be useful for monitoring longtime scale events in other GPCRs.
