Gluconokinase Activity Assay Kit (Colorimetric) (ab211092) provides a simple, sensitive and convenient method for detecting gluconokinase activity in a variety of samples such as cell and tissue lysates, and even in prokaryotes such as E. coli. In this assay, Gluconokinase converts Gluconate into 6-Phosphate-D-Gluconate in an ATP dependent manner. 6-Phosphate-D-Gluconate and ADP in turn undergo a series of reactions to form an intermediate, which reacts with the probe to form a colored product with strong absorbance (OD 450 nm).

Notes
Gluconokinase (GntK, ATP:D-gluconate 6-phosphotransferase, Gluconate Kinase; EC:2.7.1.12) is a key enzyme for degradation of gluconate. In E. coli and yeast, Gluconokinase phosphorylates gluconate into 6-Phosphate-D-Gluconate in an ATP dependent manner. Via the Hexose Monophosphate Shunt (HMS) pathway, 6- Phosphate-D-Gluconate generates ribose-5-phosphate, which is critical for nucleotides and nucleic acid synthesis.
Despite the widespread use of D-gluconate as acidity regulator in food and medicine, little is known of the mechanism of gluconate metabolism in humans.
