ID 5.6.1.5 DE proteasome ATPase. CA ATP + H2O + polypeptide = ADP + phosphate + unfolded polypeptide. CC -!- Belongs to the AAA-type superfamily and, like EC 5.6.1.4, is involved CC in channel gating and polypeptide unfolding before proteolysis in the CC proteasome. CC -!- Six ATPase subunits are present in the regulatory particle (RP) of CC 26S proteasome. CC -!- Formerly EC 3.6.4.8. //
