The transport of proline and valine by Agrobacterium tumefaciens was investigated. Proline uptake by starved cells was found to be higher in the presence of glucose than in its absence. Valine uptake, on the other hand, was lowered in the presence of glucose. Proline uptake was found to be insensitive to the action of dicyclohexyl carbodiimide (DCCD), a membrane ATPase inhibitor, whereas valine uptake appeared to show some sensitivity to this agent. The results obtained seem to suggest that the two transport systems make use of different energy stores.
