Induction of the nag regulon of Escherichia coli by N-acetylglucosamine and glucosamine: role of the cyclic AMP-catabolite activator protein complex in expression of the regulon.

Abstract excerpt

The divergent nag regulon located at 15.5 min on the Escherichia coli map encodes genes necessary for growth on N-acetylglucosamine and glucosamine. Full induction of the regulon requires both the presence of N-acetylglucosamine and a functional cyclic AMP (cAMP)-catabolite activator protein (CAP) complex. Glucosamine produces a lower level of induction of the regulon. A nearly symmetric consensus CAP-binding...
