Purification and Characterization of glpX-Encoded Fructose 1,6-Bisphosphatase, a New Enzyme of the Glycerol 3-Phosphate Regulon of Escherichia coli
… that glpX encodes a fructose 1,6-bisphosphatase (FBPase), which catalyzes the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate and phosphate. The purified FBPase was dimeric, dependent on Mn2+ for activity and exhibited an apparent Km of 35 μM for fructose 1,6-bisphosphate. The …

Thioredoxin-mediated reduction of photosynthetic carbon reduction enzymes following chilling in the light
… (PCRC). The enzyme fructose-1,6-bisphosphatase (FBPase) was isolated and characterized from both plants illuminated at low temperature as well as control plants. Isolated FBPase from both plants was effectively reduced by thioredoxin. The chilling treatment had no effect on the midpoint potential …

Field trials to phenotype transgenic tobacco plants with improved RuBP regeneration
… genes for the cyanobacterial bifunctional FBPase/SBPase and algal cytochrome c6 proteins. The bifunctional FBPase/SBPase protein catalyses two steps in the regenerative phase of the Calvin-Benson-Bassham cycle. The H-protein upregulates the complex that facilitates the conversion of glycine …

Regulation of Fructose 1,6-bisphosphatase II (GlpX) Gene Expression in Escherichia coli
… coli encodes fructose 1,6-bisphosphatase II (FBPase II), an enzyme that would appear to be redundant with FBPase I, encoded by fbp. However, glpX mutants have no apparent phenotype, while fbp mutants are unable to grow on gluconeogenic substrates as sole carbon sources, suggesting that GlpX …

Enhanced methylglyoxal formation in cystathionine γ-lyase knockout mice
… the activity of fructose-1,6-bisphosphatase (FBPase), the rate-limiting enzyme in gluconeogenesis, was significantly down-regulated, along with lower levels of its product (fructose-6-phosphate) and higher levels of its substrate (fructose-1,6-bisphosphate) in the kidney of 6-22 week-old …

Functional analyses of ζ-crystallin binding to the 3'-UTR of glutaminase (GA) mRNA
… selective stabilization of the GA mRNA. LLC-PK1- FBPase+ cells, a pH-responsive porcine kidney cell line, express four distinct GA mRNAs, that are ~2.5, 3.5, 4.5, and 5.0 kb in length. RNase H mapping indicated that three of the GA mRNAs are generated by the use of alternative polyadenylation …

Genome Scale Metabolic Modelling of Arabidopsis thaliana and Chlamydomonas reinhardtii
… demonstrated a complementary role of SBPase and FBPase in the Calvin cycle and further proposed a novel role of transaldolase in daytime metabolism under knockout conditions. Both models, were used to investigate likely coordinated changes in metabolic networks to dissipate excess energy under …

Engineering cyanobacterial genes into Glycine max (soybean) leads to increased photosynthesis and productivity
… carbon to Rubisco. The FBP1 gene encodes the FBPase/SBPase bifunctional enzyme which has the same enzymatic function as the two individual enzymes present in higher plants. These two enzymes regulate key steps in the reductive pentose-phosphate (Calvin) cycle, the primary pathway for carbon …
