The 20S particle, which is composed of NSF, SNAP and the SNARE complex, is important in fusion events. Single-particle cryo-EM and negative stain EM studies of the 20S particle and of NSF in its different nucleotide states suggest how nucleotide-dependent conformational changes in NSF may generate a force via ATP hydrolysis, providing insight into disassembly of SNARE by NSF.
