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

Frontiers 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

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

Journal 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

Methodist 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.

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

Sensors, 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).

Biohydrogen Production by the Thermophilic Bacterium Caldicellulosiruptor saccharolyticus: Current Status and Perspectives

Life, 2013
Caldicellulosiruptor saccharolyticus is one of the most thermophilic cellulolytic organisms known to date. This Gram-positive anaerobic bacterium ferments a broad spectrum of mono-, di- and polysaccharides to mainly acetate, CO2 and hydrogen.

Biosynthesis of Thiamin Pyrophosphate [PDF]

EcoSal Plus, 2009
The biosynthesis of thiamin pyrophosphate (TPP) in prokaryotes, as represented by the Escherichia coli and the Bacillus subtilis pathways, is summarized in this review. The thiazole heterocycle is formed by the convergence of three separate pathways.

Arterial Calcifications in Patients with Liver Cirrhosis Are Linked to Hepatic Deficiency of Pyrophosphate Production Restored by Liver Transplantation

Biomedicines, 2022
Liver fibrosis is associated with arterial calcification (AC). Since the liver is a source of inorganic pyrophosphate (PPi), an anti-calcifying compound, we investigated the relationship between plasma PPi ([PPi]pl), liver fibrosis, liver function, AC ...

Mechanism of squalene biosynthesis: evidence against the involvement of free nerolidyl pyrophosphate

Journal of Lipid Research, 1969
Several mechanisms that utilize farnesyl pyrophosphate and nerolidyl pyrophosphate as condensing substrates have been postulated for the asymmetric condensation reaction in squalene biosynthesis.

Inositol Pyrophosphate Pyrotechnics [PDF]

Cell 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 ...
