EC 2.7.1.193     
Accepted name: protein-Nπ-phosphohistidine—N-acetyl-D-glucosamine phosphotransferase
Reaction: [protein]-Nπ-phospho-L-histidine + N-acetyl-D-glucosamine[side 1] = [protein]-L-histidine + N-acetyl-D-glucosamine 6-phosphate[side 2]
Other name(s): nagE (gene name); N-acetyl-D-glucosamine PTS permease; EIINag; Enzyme IINag; EIICBANag
Systematic name: protein-Nπ-phospho-L-histidine:N-acetyl-D-glucosamine Nπ-phosphotransferase
Comments: This enzyme is a component (known as enzyme II) of a phosphoenolpyruvate (PEP)-dependent, sugar transporting phosphotransferase system (PTS). The system, which is found only in prokaryotes, simultaneously transports its substrate from the periplasm or extracellular space into the cytoplasm and phosphorylates it. The phosphate donor, which is shared among the different systems, is a phospho-carrier protein of low molecular mass that has been phosphorylated by EC 2.7.3.9 (phosphoenolpyruvate—protein phosphotransferase). Enzyme II, on the other hand, is specific for a particular substrate, although in some cases alternative substrates can be transported with lower efficiency. The reaction involves a successive transfer of the phosphate group to several amino acids within the enzyme before the final transfer to the substrate.

EC 3.5.99.6     
Accepted name: glucosamine-6-phosphate deaminase
Reaction: α-D-glucosamine 6-phosphate + H2O = D-fructose 6-phosphate + NH3
For diagram of UDP-N-acetylglucosamine biosynthesis, click here
Glossary: α-D-glucosamine 6-phosphate = 2-amino-2-deoxy-α-D-glucopyranose 6-phosphate
Other name(s): glucosaminephosphate isomerase (ambiguous); glucosamine-6-phosphate isomerase (ambiguous); phosphoglucosaminisomerase (ambiguous); glucosamine phosphate deaminase; aminodeoxyglucosephosphate isomerase (ambiguous); phosphoglucosamine isomerase (ambiguous); 2-amino-2-deoxy-D-glucose-6-phosphate aminohydrolase (ketol isomerizing)
Systematic name: 2-amino-2-deoxy-α-D-glucose-6-phosphate aminohydrolase (ketol isomerizing)
Comments: The enzyme uses ring opening and isomerization of the aldose-ketose type to convert the -CH(-NH2)-CH=O group of glucosamine 6-phosphate into -C(=NH)-CH2-OH, forming 2-deoxy-2-imino-D-arabino-hexitol, which then hydrolyses to yield fructose 6-phosphate and ammonia. N-Acetyl-D-glucosamine 6-phosphate, which is not broken down, activates the enzyme.

Systematic name: α-D-glucosamine 1,6-phosphomutase
Comments: The enzyme is involved in the pathway for bacterial cell-wall peptidoglycan and lipopolysaccharide biosyntheses, being an essential step in the pathway for UDP-N-acetylglucosamine biosynthesis. The enzyme from Escherichia coli is activated by phosphorylation and can be autophosphorylated in vitro by α-D-glucosamine 1,6-bisphosphate, which is an intermediate in the reaction, α-D-glucose 1,6-bisphosphate or ATP. It can also catalyse the interconversion of α-D-glucose 1-phosphate and glucose 6-phosphate, although at a much lower rate.
