RESUMO
Transcription from P2, one of the major promoters of the cell wall protein gene operon of Bacillus brevis 47, was markedly enhanced at the early stationary phase of growth. MgCl2, when added at 1 to 5 mM to the medium, inhibited this enhancement of transcription as well as shedding of the cell wall protein layers from the cell surface. MgSO4 or CaCl2 showed an effect similar to that of MgCl2. The possible coordination of the cell wall structure with regulation of the cell wall protein genes is discussed.
