Glycerol-3-phosphate dehydrogenase homologue from Schizosaccharomyces pombe.

A gene encoding an S.pombe homologue of glycerol-3-phosphate dehydrogenase was isolated from a XEMBL3 library. The clone was originally isolated because it hybridised to a rat BiP cDNA probe (1). Upon sequencing, however, it was found that there was no homology between this clone and BiP at the amino acid level. The open reading frame was used to search databases and the gene identified as an S...

Activation of mitochondrial glycerol 3-phosphate dehydrogenase by cadmium ions.

Mitochondrial glycerol 3-phosphate dehydrogenase (EC 1.1.2.1.) requires Ca2+ ions for its activity. Cadmium ions also have activatory effect on the enzyme. They activate the glycerol 3-phosphate dehydrogenase in a very narrow concentration range (1-2 mmol/l). As contrasted with calcium, strong inhibitory effect occurred at higher concentrations (3-4 mmol/l). The inhibition induced by cadmium io...

Anaerobic Glycerol-3-Phosphate Dehydrogenase and the glpD Operon Encoding Aerobic Glycerol-3-Phosphate Dehydrogenase in Escherichia coli: Further Characterization of Respiratory Control

In Escherichia coli, sn-glycerol-3-phosphate can be oxidized by two different flavo-dehydrogenases, an anaerobic enzyme encoded by the glpACB operon and an aerobic enzyme encoded by the glpD operon. These two operons belong to the glp regulon specifying the utilization of glycerol, sn-glycerol-3-phosphate, and glycerophosphodiesters. In glpR mutant cells grown under conditions of low catabolite...

Involvement of a glycerol-3-phosphate dehydrogenase in modulating the NADH/NAD+ ratio provides evidence of a mitochondrial glycerol-3-phosphate shuttle in Arabidopsis.

A mitochondrial glycerol-3-phosphate (G-3-P) shuttle that channels cytosolic reducing equivalent to mitochondria for respiration through oxidoreduction of G-3-P has been extensively studied in yeast and animal systems. Here, we report evidence for the operation of such a shuttle in Arabidopsis thaliana. We studied Arabidopsis mutants defective in a cytosolic G-3-P dehydrogenase, GPDHc1, which, ...

Biosynthesis in Escherichia coli of sn-glycerol 3-phosphate, a precursor of phospholipid. Palmitoyl-CoA inhibition of the biosynthetic sn-glycerol-3-phosphate dehydrogenase.

Homogeneous biosynthetic sn-glycerol-3-phosphate dehydrogenase (EC 1.1.1.8) of Escherichia coli was potently inhibited by palmitoyl-CoA and other long chain acyl-CoA thioesters. The concentration dependence of this inhibition was not cooperative. Enzyme activity was inhibited 50% at 1 microM palmitoyl-CoA; thus, this inhibition occurred at concentrations below the critical micellar concentratio...
