Model of the ionic layer of the yeast post-Golgi SNARE complex. Names of the residues proposed to constitute an ionic layer in the yeast Sec9/Sso1/Snc2 SNARE complex have been imposed onto the molecular structure of the neuronal SNARE complex ionic layer, represented as a Molscript-generated ribbon diagram. According to a sequence alignment–based prediction, the t-SNARE Sec9 contributes Q468 and Q622 from its first and second helices (respectively), the t-SNARE Sso1 contributes Q224, and the v-SNARE contributes R52 to the putative ionic layer.
