General description

α-Glycerophosphate dehydrogenase is a membrane protein and a flavin-linked primary dehydrogenase.

Research area: Cell Signaling

Application

α-Glycerophosphate Dehydrogenase from rabbit muscle has been used:
  • in the reaction mixture to measure the glycerol kinase activity
  • to demonstrate compartmentalized enzymatic reactions where NADH is involved
  • in the reaction mixture assay for L-fuculose-1-phosphate aldolase

Biochem/physiol Actions

α-Glycerophosphate dehydrogenase catalyzes the oxidation of L-α-glycerophosphate (Glp) to form dihydroxyacetone phosphate (DHAP) and hydrogen peroxide (H2O2). This enzyme is associated with respiratory electron transport chain, glycolysis, and phospholipid metabolism.

Unit Definition

One unit will convert 1.0 μmole of dihydroxyacetone phosphate to α-glycerophosphate per min at pH 7.4 at 25 °C.

Physical form

Crystalline suspension in 3.2 M (NH4)2SO4 and 0.1 g/L EDTA solution, pH 6.0

Preparation Note

Prepared by modification of the method of Fondy.

Analysis Note

Protein determined by biuret.

Sn-glycerol-3-phosphate dehydrogenase (GlpD) is an essential membrane enzyme, functioning at the central junction of respiration, glycolysis, and phospholipid biosynthesis. Its critical role is indicated by the multitiered regulatory mechanisms that stringently controls its expression and function. Once expressed, GlpD activity

One of the early steps in the biosynthesis of coenzyme F(420) in Methanocaldococcus jannaschii requires generation of 2-phospho-L-lactate, which is formed by the phosphorylation of L-lactate. Preliminary studies had shown that L-lactate in M. jannaschii is not derived from pyruvate
