A single amino acid substitution (Glu134-->Ala) in NhaR1 increases the inducibility by Na+ of the product of nhaA, a Na+/H+ antiporter gene in Escherichia coli.
The mutation nhaAup (antup) has now been identified as a Glu134 to Ala substitution in NhaR and designated nhaR1. This was demonstrated by sequence analysis showing that the mutant contains a wild-type nhaA but nhaR1 instead of nhaR and by the finding that nhaR1 cloned in a plasmid confers the NhaAu...
