Delipidated Ca-ATPase from vitamin E-deficient sarcoplasmic reticulum (SR) reconstituted with lipid of control SR exhibited properties similar to preparations reconstituted with lipid of vitamin E-deficient SR, namely low Ca-ATPase activity and a linear Arrhenius plot of enzyme activity. On the other hand, delipidated control SR Ca-ATPase reconstituted with lipid of vitamin E-deficient SR showed a reduction in activity by retained the discontinuity in the Arrhenius plot. These results indicated that the altered property of sarcoplasmic Ca-ATPase from vitamin E-deficient dystrophic rabbit was associated with the protein and not the lipid component.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyArticleSCOPUS
