Abstract

Osmotic stress produced by high concentrations of sucrose stimulated the high-affinity transport of glutamine in Escherichia coli cells. Glutamine transport via a low-affinity system was not affected. Osmotic stress produced by NaCl, in contrast, inhibited the transport of glutamine and some other amino acids. Maltose transport was strongly inhibited by osmotic stress.
