N-TERMINAL DOMAIN OF N-ETHYLMALEIMIDE SENSITIVE FACTOR (NSF)
|
Overview
N-ethylmaleimide-sensitive factor (NSF) is a hexameric ATPase essential, for eukaryotic vesicle fusion. Along with SNAP proteins, it disassembles, cis-SNARE complexes upon ATP hydrolysis, preparing SNAREs for trans, complex formation. We have determined the crystal structure of the, N-terminal domain of NSF (N) to 1.9 A resolution. N contains two, subdomains which form a groove that is a likely SNAP interaction site., Unexpectedly, both N subdomains are structurally similar to domains in, EF-Tu. Based on this similarity, we propose a model for a large, conformational change in NSF that drives SNARE complex disassembly.
