N-Acetyl-Glucosamin-6 phosphate regulated repression system

Commensal bacteria in the gut metabolize the mucus within the intestines, which increases the level of GlcNAc within the lumen. GlcNAc is taken up by the bacteria through their PTS system and metabolized into GlcNAc-6-P, which binds the repressor protein nagC. If nagC is bound to GlcNAc-6-P it loses ist abilities to bind DNA, and therefore ist respective regulation activity. In our case, nagC can consequently not serve as a repressor of the nagBACDE, anymore. Thus, a repressor Protein, the Mnt repressor of the Lambda Phage, can be expressed. The Mnt repressor binds to the Mnt promoter inhibiting the transcription of downstream genes. If GlcNAc-6-P is not present nagC remains active repressing the Expression of the MntR.
