A Zymomonas mobilis mutant was identified by Steve Brown and colleagues demonstrating sodium acetate
tolerance that has potential importance in biofuel development.
Over-expression of the sodium-proton antiporter
gene nhaA confers the elevated AcR sodium acetate tolerance
phenotype. A structural model for the NhaA sodium proton
antiporter was constructed to provide mechanistic insights.
