Catabolite repression of alpha-amylase gene expression in Bacillus subtilis involves a trans-acting gene product homologous to the Escherichia coli lacl and galR repressors.

Abstract excerpt

Expression of the alpha-amylase gene of Bacillus subtilis is controlled at the transcriptional level, and responds to the growth state of the cell as well as the availability of rapidly metabolizable carbon sources. Glucose-mediated repression has previously been shown to involve a site near the transcriptional start-point of the amyE gene. In this study, a transposon insertion mutation was characterized which...
