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)
Branched-chain amino acids are the most abundant amino acids in proteins. The Bacillus subtilis ilv-leu operon is involved in the biosynthesis of branched-chain amino acids. This operon exhibits a(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)
