While assembly of the complex can take place under only conditions where a components and a membrane is present, disassembly requires that NSF can hydrolyze ATP. (wikipedia.org)
Further studies demonstrated that the ATP hydrolysis step occurs prior to a calcium ion mediated fusion event, and thus revealing, that SNAP and NSF proteins initiate disassembly the 20S complex before the docking event takes place directly at the membrane. (wikipedia.org)

4) Lysosomal fusion with autophagosomes also requires SNAREs, including VAMP8, syntaxin-17 and SNAP29. (biomedcentral.com)
