Description générale

Research area: Cell Signaling

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.

Actions biochimiques/physiologiques

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.

Définition de l'unité

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.

Forme physique

Stabilized solution in Tris buffer, pH 7.3

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
