The 'scavenger' m(7)GpppX pyrophosphatase activity of Dcs1 modulates nutrient-induced responses in yeast [PDF]

, 2004
Dcs1, the m(7)GpppX pyrophosphatase of Saccharomyces cerevisiae, has been reported to 'scavenge' capped 51 end fragments generated by 3'-->5' mRNA degradation.

The inorganic pyrophosphatase activity of erythrocytes in favism

The Turkish Journal of Pediatrics, 1961
Inorganic pyrophosphatase activity of erythrocytes was found to be decreased in subjects affected by the glucose-6-phosphate dehydrogenase deficiency. During the acute hemolytic episode of favism, pyrophosphatase activity shows a further critical fall.

Plasmodium falciparum utilizes pyrophosphate to fuel an essential proton pump in the ring stage and the transition to trophozoite stage.

PLoS Pathogens, 2023
During asexual growth and replication cycles inside red blood cells, the malaria parasite Plasmodium falciparum primarily relies on glycolysis for energy supply, as its single mitochondrion performs little or no oxidative phosphorylation.

H⁺-Translocating Membrane-Bound Pyrophosphatase from Rhodospirillum rubrum Fuels Escherichia coli Cells via an Alternative Pathway for Energy Generation

Microorganisms, 2023
Inorganic pyrophosphatases (PPases) catalyze an essential reaction, namely, the hydrolysis of PPi, which is formed in large quantities as a side product of numerous cellular reactions.

LcpB Is a Pyrophosphatase Responsible for Wall Teichoic Acid Synthesis and Virulence in Staphylococcus aureus Clinical Isolate ST59

Frontiers in Microbiology, 2021
The community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) causes severe pandemics primarily consisting of skin and soft tissue infections. However, the underlying pathomechanisms of the bacterium are yet to fully understood.

RppH can faithfully replace TAP to allow cloning of 5′-triphosphate carrying small RNAs

MethodsX, 2019
RNA interference was first described in the nematode Caenorhabditis elegans. Ever since, several new endogenous small RNA pathways have been described and characterized to different degrees.

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

Mutagenesis Reveals That the OsPPa6 Gene Is Required for Enhancing the Alkaline Tolerance in Rice

Frontiers in Plant Science, 2019
Alkaline stress (AS) is one of the abiotic stressful factors limiting plant’s growth and development. Inorganic pyrophosphatase is usually involved in a variety of biological processes in plant in response to the abiotic stresses.

PPA2 Deficiency in 2 Sisters

JACC: Case Reports, 2023
Inorganic pyrophosphatase 2 (PPA2) deficiency is a genetic cause of sudden cardiac death, often triggered by viral infection or alcohol consumption. Literature on management is limited because most cases are diagnosed post mortem.
