Abstract excerpt
The chromosomally encoded TetA(L) protein of Bacillus subtilis is a multifunctional tetracycline-metal/H(+) antiporter that also exhibits monovalent cation/H(+) antiport activity and a net K(+) uptake mode. In this study, B. subtilis mutant strains JC112 and JC112C were found to be representative of two phenotypic types of tetA(L) deletion strains that are generated in the same selection. Both strains exhibited...
