The integration of biophysical data from multiple sources is critical for developing accurate structural models of large multiprotein systems and their regulators. Mass spectrometry (MS) can be used to measure the insertion location for a wide range of topographically sensitive chemical probes, and such insertion data provide a rich, but disparate set of modeling restraints. We have developed a software...
Members of the kinesin-13 subfamily use motor domains in an unconventional fashion to initiate microtubule (MT) depolymerization at MT ends, suggesting unique conformational transitions for lattice engagement, end adaptation, or both. Using hydrogen-deuterium exchange and electron microscopy, we explored conformational changes in free dimeric mitotic centromere-associated kinesin (MCAK) and when bound...
Assessing the functional outcome of protein interactions in structural terms is a goal of structural biology, however most techniques have a limited capacity for making structure–function determinations with both high resolution and high throughput. Mass spectrometry can be applied as a reader of protein chemistries in order to fill this void, and enable methodologies whereby protein structure–function...
