Gene controlling the uptake of shikimic acid by Escherichia coli.

Pittard, James (University of Melbourne, Melbourne, Australia), and B. J. Wallace. Gene controlling the uptake of shikimic acid by Escherichia coli. J. Bacteriol. 92:1070-1075. 1966.-Mutants possessing an impaired ability to take up exogenously supplied shikimic acid were isolated. Mutants showing either a complete or partial loss of this activity were found. The mutations have been mapped on the Escherichia coli chromosome and occur in a single gene, situated near to the cluster of genes concerned with histidine biosynthesis. The uptake of dehydroshikimic acid was also affected by these mutations, suggesting a common mechanism for the uptake of these two related intermediates of aromatic biosynthesis.
