Abstract:
:We previously reported that novel Mg(2+)-ATPases were induced in rat liver peroxisomes by clofibrate administration and that these activities consisted of at least two types of enzymes, N-ethylmaleimide (NEM)-sensitive and -resistant. Here we present evidence that neither of these major peroxisomal ATPases is associated with the 70-kDa peroxisomal membrane protein (PMP70), because: (i) proteinase K treatment of peroxisomes resulted in inactivation of only NEM-sensitive ATPase, whereas disappeared PMP70 completely; (ii) NEM-sensitive ATPase activity was barely immunoprecipitated with anti-PMP70 IgG; (iii) the solubilized ATPases behaved differently from PMP70 on native PAGE; and finally (iv), the major peroxisomal ATPases were separated from PMP70 on gel filtration chromatography.
