<!--

~~SNARE proteins form a complex that leads to membrane fusion between vesicles~~, ~~organelles~~, ~~and plasma membrane in all eukaryotic cells. We report~~ the ~~1.7A resolution structure of~~ the ~~SNARE complex that mediates exocytosis~~ at ~~the plasma membrane in the yeast Saccharomyces cerevisiae~~. ~~Similar to its neuronal and endosomal homologues~~, the S. ~~cerevisiae SNARE complex forms a parallel four~~-~~helix bundle in the center of which is an ionic layer. The S. cerevisiae SNARE complex exhibits increased helix bending near the ionic layer, contains water~~-filled cavities in the complex core, and exhibits reduced thermal stability relative to mammalian SNARE complexes. Mutagenesis experiments suggest that the water-filled cavities contribute to the lower stability of the S. cerevisiae complex.

-SNARE proteins form a complex that leads to membrane fusion between vesicles, organelles, and plasma membrane in all eukaryotic cells. We report the 1.7A resolution structure of the SNARE complex that mediates exocytosis at the plasma membrane in the yeast Saccharomyces cerevisiae. Similar to its neuronal and endosomal homologues, the S. cerevisiae SNARE complex forms a parallel four-helix bundle in the center of which is an ionic layer. The S. cerevisiae SNARE complex exhibits increased helix bending near the ionic layer, contains water-filled cavities in the complex core, and exhibits reduced thermal stability relative to mammalian SNARE complexes.
