Inositol Pyrophosphate Pyrotechnics [PDF]

open access: yesCell Metabolism, 2007
Physiologic roles of highly phosphorylated inositol phosphates, including those containing pyrophosphate groups, have been the focus of much recent interest. In the April 6, 2007 issue of Science, two papers (Lee et al., 2007; Mulugu et al., 2007) demonstrate the occurrence of a novel inositol pyrophosphate molecule in yeast and elucidate its role in ...

Thermodynamic examination of the pyrophosphate sensor helix in the thiamine pyrophosphate riboswitch [PDF]

open access: yesRNA, 2011
Riboswitches are functional mRNA that control gene expression. Thiamine pyrophosphate (TPP) binds tothi-box riboswitch RNA and allosterically inhibits genes that code for proteins involved in the biosynthesis and transport of thiamine. Thiamine binding to the pyrimidine sensor helix and pyrophosphate binding to the pyrophosphate sensor helix cause ...

Studies on inorganic pyrophosphate in pyrophosphate arthropathy [PDF]

open access: yes, 1994
Age, metabolic disease and familial tendency all predispose to CPPD crystal deposition. However, the effects of these predisposing factors on articular PPi metabolism have not been investigated.

Influence of the radioactive concentration of the in vitro stability of Tc-99m(sn)-pyrophosphate [PDF]

open access: yesJournal of the Serbian Chemical Society, 1999
The in vitro stability of 99m Tc(Sn)-pyrophosphate solutionwas examined in dependence on the preparation conditions of the samples, the radioactive concentration of 99m Tc in the kit and the time elapsed after labeling.

It Takes a Village: Multimodality Imaging of Cardiac Amyloidosis

open access: yesMethodist DeBakey Cardiovascular Journal, 2022
Cardiac amyloidosis (CA) is the buildup and infiltration of amyloid plaque in cardiac muscle. An underdiagnosed form of restrictive cardiomyopathy, CA can rapidly progress into heart failure.

Contribution of PPi-hydrolyzing function of vacuolar H+-pyrophosphatase in vegetative growth of Arabidopsis: Evidenced by expression of uncoupling mutated enzymes

open access: yesFrontiers in Plant Science, 2016
The vacuolar-type H+-pyrophosphatase (H+-PPase) catalyzes a coupled reaction of pyrophosphate (PPi) hydrolysis and active proton translocation across the tonoplast. Overexpression of H+-PPase improves growth in various plant species, and loss-of-function

Biochemical characterisation of the Mycobacterium tuberculosis phosphoribosyl-1-pyrophosphate synthetase (Mt-PrsA) [PDF]

open access: yes, 2001
Mycobacterium tuberculosis arabinogalactan (AG) is an essential cell wall component. It provides a molecular framework serving to connect peptidoglycan to the outer mycolic acid layer. The biosynthesis of the arabinan domains of AG and lipoarabinomannan (

A Molecular Logic Gate for the Naked-Eye Detection of Gluthatione or Pyrophosphate with a Nickel Based Bio-Sensor [PDF]

open access: yes, 2020
An inorganic water soluble Ni(II) complex offers a molecular logic gate for the naked-eye detection of pyrophosphate versus thiol derivatives. Pyrocathecol coordinated to nickel performs a thiol-michael addition click reaction in the presence of thiol ...

Iron deficiency up-regulates iron absorption from ferrous sulphate but not ferric pyrophosphate and consequently food fortification with ferrous sulphate has relatively greater efficacy in iron-deficient individuals [PDF]

open access: yes, 2010
Fe absorption from water-soluble forms of Fe is inversely proportional to Fe status in humans. Whether this is true for poorly soluble Fe compounds is uncertain.

TAMRA/TAMRA Fluorescence Quenching Systems for the Activity Assay of Alkaline Phosphatase

open access: yesSensors, 2017
We introduce two types of fluorescence-quenching assay for alkaline phosphatases (APs) by using a carboxytetramethyl-rhodamine (TAMRA)-labeled phosphate-binding tag molecule (TAMRA-Phos-tag).
