Chains	Enzyme Name	Description	Catalytic Residues
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.
