摘要
Folded or not? Ion mobility-mass spectrometry investigation of an activated macromolecular protein complex lends insight into the structures of intermediates formed in the dissociation process. The activated ions of human tetrameric transthyretin populate partially folded intermediate states (see picture; folded subunits in blue, partially unfolded subunits in red) prior to dissociation.
