In vivo and in vitro, these proteins form a tight complex. Assembly is associated with a large increase in alpha-helical content, suggesting that major structural and conformational changes are associated with the assembly reaction. Limited proteolysis by trypsin, chymotrypsin, and proteinase K of the ternary complex formed from recombinant proteins lacking their membrane anchors revealed a SDS-resistant minimal core. The components of this core complex were purified and characterized by N-terminal sequencing and mass spectrometry. They include a slightly shortened synaptobrevin fragment, C- and N-terminal fragments of SNAP-25, and a C-terminal fragment of syntaxin that is slightly larger than the previously characterized H3 domain. Recombinant proteins corresponding to these fragments are sufficient for assembly and disassembly. In addition, each of the two SNAP-25 fragments can individually form complexes with syntaxin and synaptobrevin, suggesting that they both contribute to the assembly of the SNARE complex. Upon complex assembly, a large increase in alpha-helical content is observed along with a significantly increased melting temperature (Tm). Like the full-length complex, the minimal complex tends to form an oligomeric species; global analysis of equilibrium ultracentrifugation data suggests a monomer-trimer equilibrium exists. These conserved biophysical properties may thus be of fundamental importance in the mechanism of membrane fusion."xsd:string |
