Abstract/OtherAbstract:
ATP-dependent H+ -pump activity was found in inverted vesicles of Methanosarcina mazei Gö1 by using acridine orange as a fluorescent probe. The H+ -pump activity specifically required both Mg and sulfite ions, but azide, an inhibitor of F0F1-ATPase, did not inhibit the activity. The membranes prepared from M. mazei also had an Mg-ATPase activity, and at least the presence of vacuolar-type ATPase was detected.
