Studies on the entry of fructose-2,6-bisphosphate into chloroplasts.

Plant physiology

Smeekens S, Macdonald FD, Buchanan BB.
PMID: 16666695
Plant Physiol. 1989 Apr;89(4):1270-4. doi: 10.1104/pp.89.4.1270.

The regulatory metabolite fructose-2,6-bisphosphate (Fru-2,6-P(2)) has an important function in controlling the intermediary carbon metabolism of leaves. Fru-2,6-P(2) controls two cytosolic enzymes involved in the interconversion of fructose-6-phosphate and fructose-1,6-bisphosphate (fructose-1,6-bisphosphatase and pyrophosphate, fructose-6-phosphate 1-phosphotransferase) and thereby controls the...

Phosphoribosyl pyrophosphate and the measurement on inorganic pyrophosphate in plant tissues.

Planta

Dancer JE, Ap Rees T.
PMID: 24212348
Planta. 1989 Feb;177(2):261-4. doi: 10.1007/BF00392814.

This work provides further evidence that plants contain appreciable amounts of inorganic pyrophosphate (PPi), and that breakdown of phosphoribosyl pyrophosphate (PPRibP) does not contribute significantly to the PPi detected in plant extracts. Inorganic pyrophosphate in extracts of the roots...

Measurement of the inorganic pyrophosphate in tissues of Pisum sativum L.

Planta

Edwards J, Rees TA, Wilson PM, Morrell S.
PMID: 24254055
Planta. 1984 Sep;162(2):188-91. doi: 10.1007/BF00410217.

Purified pyrophosphate: fructose 6-phosphate 1-phosphotransferase (EC 2.7.1.90) was used to measure the inorganic pyrophosphate in unfractionated extracts of tissues of Pisum sativum L. The fructose 1,6-bisphosphate produced by the above enzyme was measured by coupling to NADH oxidation via...

Pyrophosphate Fructose-6-P 1-Phosphotransferase from Tomato Fruit : Evidence for Change during Ripening.

Plant physiology

Wong JH, Kiss F, Wu MX, Buchanan BB.
PMID: 16667740
Plant Physiol. 1990 Oct;94(2):499-506. doi: 10.1104/pp.94.2.499.

Three forms of pyrophosphate fructose-6-phosphate 1-phosphotransferase (PFP) were purified from both green and red tomato (Lycopersicon esculentum) fruit: (a) a classical form (designated Q(2)) containing alpha- (66 kilodalton) and beta- (60 kilodalton) subunits; (b) a form (Q(1)) containing a...

The subcellular location and characteristics of pyrophosphate-fructose-6-phosphate 1-phosphotransferase from suspension-cultured cells of soybean.

Planta

Macdonald FD, Preiss J.
PMID: 24241857
Planta. 1986 Feb;167(2):240-5. doi: 10.1007/BF00391421.

The cytoplasm was identified as the probable location of pyrophosphate-fructose-6-phosphate 1-phosphotransferase (EC 2.7.1.90) in suspension-cultured cells of soybean (Glycine max L.). The characteristics of the partially purified enzyme were investigated. The activity was strongly dependent on the presence of...

Molecular and kinetic characterisation of sugarcane pyrophosphate: fructose-6-phosphate 1-phosphotransferase and its possible role in the sucrose accumulation phenotype.

Functional plant biology : FPB

Groenewald JH, Botha FC.
PMID: 32689381
Funct Plant Biol. 2007 Jun;34(6):517-525. doi: 10.1071/FP06213.

The amount of pyrophosphate: fructose-6-phosphate 1-phosphotransferase (PFP) activity in sugarcane internodal tissue is inversely correlated with sucrose content. To help elucidate this apparent role of PFP in sucrose accumulation in sugarcane we have determined its molecular and kinetic properties....

Effects of 2,4-dinitrophenol and anoxia on the inorganic-pyrophosphate content of the spadix of Arum maculatum and the root apices of Pisum sativum.

Planta

Dancer JE, Rees TA.
PMID: 24212910
Planta. 1989 Jun;178(3):421-4. doi: 10.1007/BF00391871.

This work was done to determine whether the inorganic-pyrophosphate (PPi) content of plant tissues changes when the rate of glycolysis is altered. Treatment of excised clubs of the spadix of Arum maculatum L. and root apices of Pisum sativum...
