## Abstract Several independent assay procedures were used to estimate the activities of the enzyme constituents of the phosphoenolpyruvate‐sugar phosphotransferase system (PTS) in osmotically shocked bacterial membrane vesicles. The soluble enzymes of the system were found to be in association wit
