Abstract
A purified membrane fraction featuring ATPase activity was isolated from cotyledon tissue of Phaseolus vulgaris at different stages of germination. The fraction is enriched in both basal and Na+-K+-stimulated ATPase and is relatively free of contamination by fragments of mitochondrial membrane and microsomes. The isolated membranes have been tentatively identified as partially purified plasma membrane.Keywords
