abstract：:The six- and seven-subunit Na+/H+ antiporters (Mrp) are widely distributed in bacteria. They are reported to be integral for pH homeostasis in alkaliphilic bacteria when adapting to high pH environments. In this study, operons encoding for the six-subunit Na+/H+ antiporters were found in the genomes of all studied Die...
