Osmoregulation in Bacillus subtilis under potassium limitation: a new inducible K+stimulated, VO4 inhibited ATPase

Abstract

Bacillus subtilis exhibited an inducible K+transporting ATPase activity with apparent K-m of 12,9 muM when cultivated on a synthetic medium containing less than 400 mumM K+.
