Absence of correlation between rates of cell wall turnover and autolysis shown by Bacillus subtilis mutants.

abstract：:Bacillus subtilis contains three Fur homologs: Fur, PerR, and Zur. Despite significant sequence similarities, they respond to different stimuli and regulate different sets of genes. DNA target site comparisons indicate that all three paralogs recognize operators with a core 7-1-7 inverted repeat. The corresponding con...
