glmS riboswitch binding to the glucosamine-6-phosphate α-anomer shifts the pK(a) toward neutrality

The glmS riboswitch regulates gene expression through a self-cleavage activity. The reaction is catalyzed with the assistance of the metabolite cofactor glucosamine-6-phosphate (GlcN6P), whose amino group is proposed to serve as the general acid during the reaction. This reaction is pH-dependent wit...
