Photoactivated Cross-Linking Mass Spectrometry for Probing Multidomain Protein Dynamics in Inducible Nitric Oxide Synthase.
Cross-linking mass spectrometry (XL-MS) with photoactivatable reagents has been increasingly applied to probe protein conformational dynamics; however, its sensitivity to shifts in conformational equilibrium involving transient, sparsely populated docked states within multidomain proteins remains largely unexplored. Ma...
