Roles of type II H+-PPases and PPsPase1/PECP2 in early developmental stages and PPi homeostasis of Arabidopsis thaliana

Frontiers in Plant Science, 2023
The regulation of intracellular pyrophosphate (PPi) level is crucial for proper morphogenesis across all taxonomic kingdoms. PPi is released as a byproduct from ~200 metabolic reactions, then hydrolyzed by either membrane-bound (H+-PPase) or soluble ...

Evolutionary aspects of inorganic pyrophosphatase [PDF]

FEBS Letters, 1999
Based on the primary structure, soluble inorganic pyrophosphatases can be divided into two families which exhibit no sequence similarity to each other. Family I, comprising most of the known pyrophosphatase sequences, can be further divided into prokaryotic, plant and animal/fungal pyrophosphatases.

Heterologous expression and purification of membrane-bound pyrophosphatases

, 2011
Membrane-bound pyrophosphatases (M-PPases) are enzymes that couple the hydrolysis of inorganic pyrophosphate to pumping of protons or sodium ions. In plants and bacteria they are important for relieving stress caused by low energy levels during anoxia ...

Effects of microbial population and culture phosphate composition on the activity of pyrophosphatases from soil microorganisms

, 1977
The quantity of intracellular pyrophosphatases produced in mixed cultures was not related to pyrophosphate or orthophosphate concentration in the culture medium, but high pyrophosphate concentration initially depressed microbial growth, delayed the first

Crystal Structure of Inorganic Pyrophosphatase From Schistosoma japonicum Reveals the Mechanism of Chemicals and Substrate Inhibition

Frontiers in Cell and Developmental Biology, 2021
Soluble inorganic pyrophosphatases (PPases) are essential for facilitating the growth and development of organisms, making them attractive functional proteins.

Transcriptome profiling of Nudix hydrolase gene deletions in the thermoacidophilic archaeon Sulfolobus acidocaldarius

Frontiers in Microbiology, 2023
Nudix hydrolases comprise a large and ubiquitous protein superfamily that catalyzes the hydrolysis of a nucleoside diphosphate linked to another moiety X (Nudix).

Self-incompatibility in Papaver targets soluble inorganic pyrophosphatases in pollen

, 2006
In higher plants, sexual reproduction involves interactions between pollen and pistil. A key mechanism to prevent inbreeding is self-incompatibility through rejection of incompatible ('self') pollen(1). In Papaver rhoeas, S proteins encoded by the stigma

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

Advanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.
