pubmed:abstractText |
Active transport vesicles of Escherichia coli were shown to possess low levels of energy-independent and energy-dependent nicotinamide nucleotide transhydrogenase activities. Breakage of such vesicles in a French pressure cell resulted in a fraction which had an 8-10-fold increased respiration- and ATP-driven transhydrogenase activities. Stimulation of the ATPase activity in vesicles with Triton X-100 was also paralledled by a 2-fold increase in the energy-independent transhydrogenase. Disruption of the vesicles similarly resulted in increases in the energy-independent transhydrogenase, NADH and succinate oxidase activities but a decrease in succinate supported proline uptake. In the light of these findings, the "sidedness' of the vesicle membranes is discussed.
