Metabolite Identification
Common NameGlucosamine 6-phosphate
DescriptionGlucosamine 6-phosphate, also known as GLCN-6-p or glucose-6-phosphoric acid, belongs to the class of organic compounds known as hexose phosphates. These are carbohydrate derivatives containing a hexose substituted by one or more phosphate groups. Glucosamine 6-phosphate is possibly soluble (in water) and a very strong basic compound (based on its pKa). Glucosamine 6-phosphate exists in all living species, ranging from bacteria to humans. Glucosamine 6-phosphate participates in a number of enzymatic reactions, within cattle. In particular, Glucosamine 6-phosphate and acetic acid can be biosynthesized from N-acetyl-D-glucosamine 6-phosphate; which is mediated by the enzyme putative N-acetylglucosamine-6-phosphate deacetylase. In addition, Glucosamine 6-phosphate can be converted into N-acetyl-D-glucosamine 6-phosphate; which is catalyzed by the enzyme glucosamine 6-phosphate N-acetyltransferase. In cattle, glucosamine 6-phosphate is involved in the metabolic pathway called the amino sugar metabolism pathway.

General function:
Cell wall/membrane/envelope biogenesis
Specific function:
Controls the flux of glucose into the hexosamine pathway. Most likely involved in regulating the availability of precursors for N- and O-linked glycosylation of proteins (By similarity).

2. Hexokinase-1
General function:
Involved in ATP binding
Specific function:
Catalyzes the phosphorylation of various hexoses, such as D-glucose, D-glucosamine, D-fructose, D-mannose and 2-deoxy-D-glucose, to hexose 6-phosphate (D-glucose 6-phosphate, D-glucosamine 6-phosphate, D-fructose 6-phosphate, D-mannose 6-phosphate and 2-deoxy-D-glucose 6-phosphate, respectively). Does not phosphorylate N-acetyl-D-glucosamine (By similarity). Mediates the initial step of glycolysis by catalyzing phosphorylation of D-glucose to D-glucose 6-phosphate (By similarity). Involved in innate immunity and inflammation by acting as a pattern recognition receptor for bacterial peptidoglycan. When released in the cytosol, N-acetyl-D-glucosamine component of bacterial peptidoglycan inhibits the hexokinase activity of HK1 and causes its dissociation from mitochondrial outer membrane, thereby activating the NLRP3 inflammasome (By similarity).
