3.6.4.6
Vesicle-fusing ATPase.
based on mapping to UniProt O75351
ATP + H(2)O = ADP + phosphate.
-!- A large family of ATP-hydrolyzing enzymes involved in the heterotypic fusion of membrane vesicles with target membranes and the homotypic fusion of various membrane compartments. -!- They belong to the AAA-type (ATPase associated with a variety of cell activities) ATPase superfamily. -!- They include peroxin, which apparently is involved in Zellweger's syndrome.
