Putative paired small multidrug resistance family proteins PsmrAB, the homolog of YvdSR, actually function as a novel two-component Na(+)/H(+) antiporter.


In this study, metagenomic DNA was screened for the Na(+)/H(+) antiporter gene from the halophilic bacteria from Daban Salt Lake using Escherichia coli KNabc lacking three major Na(+)/H(+) antiporters, and two genes psmrAB predicted to encode paired small multidrug resistance (PSMR) family proteins, the homolog of YvdSR, were finally cloned. Only the… (More)
