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.

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.

Unit Definition

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.

Physical form

Stabilized solution in Tris buffer, pH 7.3
