Abstract

The xyl operon of Bacillus subtilis is regulated at the level of transcription by xylose induction via the Xyl repressor and by catabolite repression. We have investigated the influence of ccpA, ptsH, ptsG andxylR mutations on catabolite repression of xylA expression. The results indicate that full glucose repression of the xyl operon requires CcpA, Hpr and XylR. In contrast, fructose repression depends on CcpA andHpr, but not on XylR. The ptsHl mutation relieves catabolite repression only partially, suggesting the possibility that other presently unknown signals are sensed by CcpA.
