Bovicin HC5, a lantibiotic produced by Streptococcus bovis HC5, catalyzes the efflux of intracellular potassium but not ATP.

ABSTRACT

Bovicin HC5, a broad-spectrum lantibiotic produced by Streptococcus bovis HC5, catalyzed the efflux of intracellular potassium from Streptococcus bovis JB1, a sensitive strain. The level of ATP also decreased, but this decline appeared to be caused by the activity of the F(1)F(0) ATPase rather than efflux per se.
