Abstract
Uptake of Li+ induced by the addition of proline to a cell suspension of Escherichia coli was detected using an Li+-selective electrode. This Li+ uptake was inhibited by L-azetidine 2-carboxylic acid, a competitive inhibitor of the proline transport system. Thus, direct evidence for Li+-proline cotransport via the proline transport system was obtained. Kinetic parameters of the Li+ uptake were determined.Keywords
