The GltS Na + /glutamate permease of Escherichia coli is the most extensively studied member of the ESS family of bacterial glutamate : Na + symporters. This paper presents the membrane topology analysis of the GltS with translational alkaline phosphatase and β‐galactosidase gene fusions generated by Tn phoA , nested deletions and targeted fusions. The topology model suggested by the translational fusion technique is compared with the MemGen model and discussed in detail.
