physiological function
physiological function
Rickettsia prowazekii is unable to synthesize glycerone phosphate as a substrate for the GpsA enzymatic reaction. Purified Rickettsia prowazekii transports and incorporates glycerone phosphate into phospholipids, implicating a role for GpsA in vivo as part of a rickettsial G3P acquisition pathway for phospholipid biosynthesis
physiological function
-
in transgenic Arabidopsis thaliana lines with a feedback-resistant glycerol-3-phosphate dehydrogenase gene from Escherichia coli, feedback-resistant glycerol-3-phosphate dehydrogenase is detected in the cytosol, but augmented glycerol-3-phosphate levels are observed in the cytosol as well as in chloroplasts. Glycerolipid composition and fatty acid positional distribution analyses reveal an altered fatty acid flux that affects not only the molar ratios of glycerolipid species but also their fatty acid composition. Changes in glycerol-3-phosphate metabolism cause altered expression of a broad array of genes. Transcript levels of the enzymes involved in the prokaryotic pathway are mostly induced, whereas genes of the eukaryotic pathway enzymes are largely suppressed

Crystallization/COMMENTARY
ORGANISM
UNIPROT
LITERATURE
crystal structure analysis: GlpD comprises two major domains, a soluble extramembraneous C-terminal cap domain (residues 389-501) and a N-terminal FAD-binding region, consisting of the substrate binding and base regions (residues 1-388). The dimeric enzyme is formed by monomers related by a noncrystallographic 2fold axis of symmetry and the dimer comprises the unique asymmetric unit. Electrostatic surface calculations show distinct regions of highly positive patches, located at the base region of the enzyme. These regions are likely involved with the negatively charged membrane phospholipid head groups. The cap domain, at the opposite side, exhibits highly negatively electrostatic potential, with large hydrophobic patches between these two distal regions of the enzyme, forming membrane interaction and proposed UQ-binding surfaces; structure of the native enzyme and in complex with dihydroxyacetone phosphate (2.1 A) and in separate complexes with substrate analogues, glyceraldehyde-3-phosphate (2.9 A), glyceric acid 2-phosphate (2.3 A), and phosphoenolpyruvate (2.1 A) are determined. Additionally, in complex with ubiquinone analogues, menadione (2.6 A) and 2-n-heptyl-4-hydroxyquinoline N-oxide (2.9 A)
