Lasalocid-catalyzed proton conductance in Streptococcus bovis as affected by extracellular potassium.

W R Schwingel1, D B Bates, S C Denham, D K Beede.   

Abstract

The effect of extracellular potassium on lasalocid-catalyzed proton conductance in Streptococcus bovis 24 was measured by using the fluorescent probe 9-aminoacridine. Increasing external potassium concentration resulted in decreased proton flux into S. bovis cells exposed to the ionophore. These results suggest that lasalocid catalyzes K+/H+ exchange diffusion in S. bovis cells.
