Mechanical unfolding of proteins: insights into biology, structure and folding.

abstract：:Hydrogen-deuterium exchange (HDX) mass spectrometry (MS) can provide information about proteins that can be challenging to obtain by other means. Structure/function relationships, binding interactions, and the effects of modification have all been measured with HDX MS for a diverse and growing array of signaling prote...

abstract：:Pore-forming proteins (PFPs), involved in host-pathogen interactions, are produced as soluble, generally monomeric, proteins. To convert from the soluble to the transmembrane form, PFPs assemble, in the vicinity of the target membrane, into ring-like structures, which expose sufficient hydrophobicity to drive spontane...
