The source of metabolic energy for the accumulation of methionine in cells of Escherichia coli was shown to differ from that for proline uptake. In contrast to proline uptake, methionine accumulation was sensitive to arsenate, and relatively resistant to azide or dinitrophenol. Adenosine triphosphatase mutant strains also differentiated between the two systems, consistent with the conclusion that, although proline uptake is driven directly by the energized membrane state, methionine uptake is… CONTINUE READING
