Active transport of manganese in isolated membrane vesicles of Bacillus subtilis.

abstract：:Rhodopseudomonas capsulata required potassium (or rubidium or cesium as analogs of potassium) for growth. These cations were actively accumulated by the cells by a process following Michaelis-Menten saturation kinetics. The monovalent cation transport system had Km's of 0.2 mM K+, 0.5 mM Rb+, and 2.6 mM Cs+. The rates...
