Abstract excerpt

Alkali-sensitive mutants which grow at pH 7.5 but not at pH 9.5 in Na(+)-rich media were isolated from Streptococcus faecalis ATCC 9790. One of the mutants, designated Nak1, lacked activities of both Na(+)-stimulated ATPase and KtrII (active K+ uptake by sodium ATPase). These activities were rest...
