Analysis of CcpA mutations defective in carbon catabolite repression in Bacillus megaterium.

FEMS microbiology letters - 1 Aug 1997

Kraus A, Hillen W

Abstract excerpt

Five mutations in ccpA of Bacillus megaterium with impaired functions were analysed for carbon catabolite repression. The phenotypes support the hypothesis that CcpA assumes a PurR/LacI fold. The completely inactive mutants CcpA119GE and CcpA326am cause alterations which are incompatible with tha...
