Collision induced unfolding
WebIn addition, collision induced unfolding (CIU) can provide orthogonal information relative to MS analysis of protein-ligand complexes alone, as the unfolding transitions are very sensitive to the local binding interactions developed between ligand and protein. WebThe energy necessary to initiate collision- induced unfolding (CIU) transitions is indicative of con- densed-phase folding, domain structure, and ligand binding.5–9 There are several implementations of IMS analyses, and many are coupled with the means of activating ions prior to mobility separation.

WebSpecifically, the Ruotolo group is expanding the capabilities of "collision induced unfolding" (CIU), an approach which studies protein structures by quickly removing the water which surrounds protein molecules in their normal environment, then induces their unfolding while monitoring their size and shape using a state-of-the-art tool known as ...
WebCollision-induced unfolding (CIU) was used to interrogate the unfolding of native ubiquitin and these Ubq-amino acid complexes, showing a major transition from its compact native state (∼1200 Å2) to an unfolded state (∼1400 Å2) at activation energies in the range from 8.0 to 9.0 V (entrance grid delta).
Collision induced unfolding is an ion mobility-mass spectrometry method that enables the rapid differentiation of subtly-different protein isoforms based on their unfolding patterns and stabilities.
