This entry represents the ATPase lid domain of the second AAA+ ATP-binding domain (also known as D2) of NSF proteins [1], found at the C-terminal. NFS proteins are essential membrane fusion events. They play the role of a chaperone by activating SNAP receptor proteins (SNAREs) so that they can participate in membrane fusion [1-5].	Domain

A	vesicle-fusing ATPase M-CSA #642	N-ethylmaleimide sensitive factor is responsible for the destabilisation and disassembly of the proteins in the SNARE complex thus has a key role in vesicular trafficking inside the cell. The structure described in this pdb code is of the ATP binding domain which contains the active site necessary for ATP hydrolysis: conformational changes that occur as a result of the hydrolysis lead to the breaking up of the SNARE complex. The ATP binding domain of the protein shares homology with other Rossmann fold containing proteins, particularly with E. coli DNA polymerase III.
