Anwendung

The product has been used for the measurement of pyrophosphate content of plant tissues.[1] It has also been used as a rapid, routine check of pyrophosphate content by monitoring NADH oxidation in Solanum tuberosum tuber extracts.[2]

Biochem./physiol. Wirkung

The pyrophosphate detection kit couples the production of pyrophosphate to the consumption of NADH[3].

Qualität

A coupled enzyme system containing fructose-6-phosphate kinase (pyrophosphate-dependent), aldolase, triosephosphate isomerase, and α-glycerophosphate dehydrogenase.

Prinzip

Two moles of NADH are oxidized to NAD+ per mole of pyrophosphate consumed. The reaction is monitored spectrophotometrically at 340 nm.
The reagent can be used to detect 10-100 nmoles of pyrophosphate.

Angaben zur Herstellung

Dissolve the contents of one vial of Pyrophosphate Reagent in 4.0 mL of water.

Pyrophosphate (PPi) was measured in pea (Pisum sativum L.) and corn (Zea mays L.) tissues by using an enzymic method based on PPi-dependent phosphofructokinase (PPi-PFK). Different organs of pea and corn seedlings were extracted to determine if PPi is present

Terpenoids represent the largest family of natural products. Their structural diversity is largely due to variable skeletons generated by terpene synthases. However, terpene skeletons found in nature are much more than those generated from known terpene synthases. Most promiscuous terpene

N6-threonylcarbamoyl adenosine (t6A) is a nucleoside modification found in all kingdoms of life at position 37 of tRNAs decoding ANN codons, which functions in part to restrict translation initiation to AUG and suppress frameshifting at tandem ANN codons. In Bacteria

Pretreatment of discs excised from developing tubers of potato (Solanum tuberosum L.) with 10 millimolar sodium fluoride induced a transient increase in 3-phosphoglycerate content. This was followed by increases in triose-phosphate, fructose 1,6-bisphosphate and hexose-phosphate (glucose 6-phosphate + fructose 6-phosphate

Class 1 plant hemoglobins (phytoglobins) are upregulated during low-oxygen stress and participate in metabolism and cell signaling via modulation of the levels of nitric oxide (NO). We studied the effects of overexpression and knockdown of the class 1 phytoglobin gene
