Allosteric regulation of glucosamine-6-phosphate deaminase (NagB) and growth of Escherichia coli on glucosamine.

Journal of bacteriology - 1 Oct 2009

Abstract excerpt

Growth on N-acetylglucosamine (GlcNAc) produces intracellular N-acetylglucosamine-6-phosphate (GlcNAc6P), which affects the regulation of the catabolism of amino sugars in Escherichia coli in two ways. First, GlcNAc6P is the inducing signal for the NagC repressor, and thus it increases the expression of the enzymes of the nagE-nagBACD operon. Second, it is the allosteric activator of glucosamine-6P (GlcN6P)...
