Aminoacyl-tRNA synthetase gene regulation in Bacillus subtilis: induction, repression and growth-rate regulation.

Abstract excerpt

The thrS gene in Bacillus subtilis is specifically induced by starvation for threonine and is, in addition, autorepressed by the overproduction of its own gene product, the threonyl-tRNA synthetase. Both methods of regulation employ an antitermination mechanism at a factor-independent transcription terminator that occurs just upstream of the start codon. The effector of the induction mechanism is thought to be...
