General description
Research area: Cell Signaling
Glycerol kinase is encoded by the GK gene on chromosome Xp21.2. Glycerol kinase is predominantly active in the liver.
Glycerol kinase is encoded by the GK gene on chromosome Xp21.2. Glycerol kinase is predominantly active in the liver.
Application
Glycerokinase from Bacillus stearothermophilus has been used in steady-state kinetics studies.
Biochem/physiol Actions
Glycerol kinase catalyzes tge MgATP-dependent phosphorylation of glycerol to produce sn-glycerol-3-phosphate and is the rate limiting enzyme in the utilization of glycerol. It is also subject to feedback regulation by fructose-1,6-bisphosphate.Oxidized glycerol-3-phosphate results in dihydroxyacetone phosphate which enters either glycolysis or gluconeogenesis. Elevated glycerol is observed in glycerol kinase deficiency leading to pseudohypertriglyceridemia.
Physical form
Stabilized solution in Tris buffer, pH 7.3
Other Notes
One unit will convert 1.0 μmole of glycerol and ATP to L-α-glycerophosphate and ADP per min at pH 9.8 at 25 °C in a coupled system with PK/LDH.

Carbon-carbon bond formation is one of the most challenging reactions in synthetic organic chemistry, and aldol reactions catalysed by dihydroxyacetone phosphate-dependent aldolases provide a powerful biocatalytic tool for combining C-C bond formation with the generation of two new stereo-centres, with

The activity of glycerol kinase is rate-limiting in the metabolism of glycerol by cells of Escherichia coli. A mutant strain producing a glycerol kinase resistant to inhibition by fructose-1,6-diphosphate grows faster than its wild-type parent on glycerol as the sole

Fructose-1 ,6-diphosphate is a feedback inhibitor of the catabolic enzyme, glycerol kinase, in Escherichia coli. A mutant was isolated which produced a desensitized enzyme. Glucose was no longer as effective in preventing the utilization of exogenous glycerol by cells which

We report a case of a male infant with the association of pseudohypertriglyceridemia, hypoadrenalism (hyponatremia, hyperpotasemia, dehydration), high creatine phosphokinase level (possible Duchenne's muscular dystrophy, DMD) and diagnosed contiguous gene deletion syndrome in Xp21. A 1-month-old male term infant was
