In Bacillus subtilis cells, the GTP level decreases and the ATP level increases upon a stringent response. This reciprocal change in the concentrations of the substrates of RNA polymerase affects the(More)
The Bacillus subtilis ilv-leu operon involved in the biosynthesis of branched-chain amino acids is under negative regulation mediated by TnrA and CodY, which recognize and bind to their respective(More)
The Bacillus subtilis ilv-leu operon is involved in the synthesis of branched-chain amino acids (valine, isoleucine, and leucine). The two- to threefold repression of expression of the ilv-leu operon(More)
