<p><i>In vivo</i> full-length Sx consists of an N-peptide preceding an N-terminal α-helical bundle (the H<sub>abc</sub> domain), a SNARE motif (the H3 helix) and a C-terminal transmembrane region. We used soluble Sx1 and Sx4 constructs lacking the transmembrane domain for experiments reported here. ΔN indicates Sx constructs lacking the N-peptide. Munc18 and SNAP25 and VAMP2 constructs used in these experiments are also shown. The positions of engineered fusion tags and protease cleavage sites are as indicated.</p>
