ADP-specific Glucokinase is an ADP-dependent glucokinase (EC 2.7.1.147), with its gene derived from Pyrococcus furiosus. It exists as a dimer, with a monomer molecular weight of 47 kD. It uses ADP as the phosphate donor to catalyze the conversion of glucose to glucose-6-phosphate. This product is recombinantly expressed in E. coli, can tolerate temperatures up to 90°C, and has an optimal temperature of 50°C.
Reaction formula
Glucose + ADP →Glucose-6-phosphate + AMP
Product Properties
Source: Expressed in E. coli
Label: N-His & C-His
Purity: ≥ 90% (analyzed by SDS-PAGE)
Molecular weight: 100 kDa
Buffer: 20 mM Tris-HCl, 500 mM NaCl, 10% Glycerol, pH 7.5.
Activity: ≥500 U/mg protein
Unit definition: One unit of enzyme activity is defined as the amount of enzyme required to consume 1.0 μmol of ADP per minute under conditions of 50°C and pH 7.5.
Usage Instructions
1. Add the substrate and 10 mM MgCl₂ to the reaction system; adjust the pH to 7.5 with appropriate buffer salts, then add a suitable amount of ADP-specific Glucokinase (as needed for the reaction);
2. After mixing, incubate the sample at 50°C for 4 hours or overnight.
【Note】 When scaling up the reaction system, adjust the incubation time or enzyme dosage according to actual conditions; low-speed shaking can be used for mixing.
【Note】 Most common biological buffers (e.g., Tris or PBS) are applicable. Buffers outside this pH range (e.g., acetate buffer) may be usable, but the incubation time or enzyme dosage needs to be optimized based on actual conditions.
