N- to C-Terminal SNARE Complex Assembly Promotes Rapid Membrane Fusion

Abstract:
Assembly of the soluble N-ethylmaleimidesensitive factorattachment protein receptors (SNAREs) syntaxin 1, SNAP-25, andsynaptobrevin 2 is thought to be the driving force for the exocytosisof synaptic vesicles. However, whereas exocytosis is triggeredat a millisecond time scale, the SNARE-mediated fusion of liposomesrequires hours for completion, which challenges the idea ofa key role for SNAREs in the final steps of exocytosis. We foundthat liposome fusion was dramatically accelerated when a stabilizedsyntaxin/SNAP-25 acceptor complex was used. Thus, SNAREs dohave the capacity to execute fusion at a speed required forneuronal secretion, demonstrating that the maintenance of acceptorcomplexes is a critical step in biological fusion reactions.
