Energy coupling for methionine transport in Escherichia coli.

ABSTRACT

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 not. Methionine transport is similar to that of other osmotic shock-sensitive systems in its direct utilization of adenosine 5'-triphosphate or a related compound as energy source.
