일반 설명

Research area: Cell Signaling

Glycerol kinase is encoded by the GK gene on chromosome Xp21.2. Glycerol kinase is predominantly active in the liver.

애플리케이션

Glycerokinase from Bacillus stearothermophilus has been used in steady-state kinetics studies.

생화학적/생리학적 작용

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.

단위 정의

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.

물리적 형태

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

Herein we measure the effect of four adaptive non-synonymous mutations to the glycerol kinase (glpK) gene on catalytic function and regulation, to identify changes that correlate to increased fitness in glycerol media. The mutations significantly reduce affinity for the allosteric
