1 Assembly and Comparison of Plasma Membrane SNARE Acceptor Complexes
Alex J.B. Kreutzberger, Binyong Liang, Volker Kiessling, Lukas K. Tamm  Biophysical Journal  Volume 110, Issue 10, Pages (May 2016) DOI: /j.bpj Copyright © 2016 Biophysical Society Terms and Conditions

2 Figure 1 Interactions between synaptobrevin-2 proteoliposomes and planar-supported bilayers with different SNARE acceptor complexes. (a) Schematic diagram of preassembled ΔN complex (left), DPC-preassembled 1:1 syx:SN25 complex (middle), and bilayer-assembled syx:d-SN25 complex (right) (adapted from Liang et al. (15)). (b) Docking of synaptobrevin-2 proteoliposomes to ΔN complex, syntaxin-1a:SNAP-25 complex assembled in DPC and CHAPS (left), syntaxin-1a assembled with d-SNAP-25 at indicated ratios (middle), and syntaxin-1a and d-SNAP-25 only (right). (c) Fusion efficiencies (% fused of all docked) of synaptobrevin-2 proteoliposomes with different SNARE complexes. (d and e) Fusion kinetics of synaptobrevin-2 proteoliposomes with colors as indicated in bar graphs. The kinetic curves are cumulative distribution functions derived from hundreds of single vesicle fusion events. The statistics are given in Table S1. To see this figure in color, go online.
