KINETIC-PROPERTIES OF MAIZE GERM CYTOPLASMIC INORGANIC PYROPHOSPHATASE

, 2015
An alkaline inorganic pyrophosphatase (pyrophosphate hydrolase EC 3.6. 1. 1.) was purified from maize (Zea mays) germ. This enzyme showed high specificty for inorganic pyrophosphate (PPi) with a K(m) value of 4.7 x 10(-5) M. The pH optimum was 8.0 to 8.5,

A Functional Genomics Approach to the Plant Soluble Pyrophosphatase Family [PDF]

, 2006
Although the activities of soluble pyrophosphatases were shown to be essential for a number of prokaryotes and eukaryotes, plants were assumed to lack cytoplasmic soluble pyrophosphatase activity and vacuolar membrane bound proton-pumping pyrophosphatase

Effect of inorganic phosphates on the activity of alkaline inorganic pyrophosphatase in sorghum caryopsis raised through liquid culture

, 1999
1012-1016Detached ears of sorghum (Sorghum vulgare) were cultured in complete liquid medium containing Pi or PPi (20mM).Effect of these inorganic phosphates on conversion of sucrose to starch in relation to the activity of alkaline inorganic ...

Enhancement of Activity of Thermophilic Inorganic Pyrophosphatase Ton1914 via Site-Directed Mutagenesis

Inorganic pyrophosphatase (PPase) is an enzyme that catalyzes the hydrolysis of pyrophosphate (PPi) into two phosphates. Ton1914, a thermophilic inorganic pyrophosphatase derived from Thermococcus onnurineus NA1, has good thermal stability and an ...

Method for real-time detection of inorganic pyrophosphatase activity

, 2001
A sensitive and simple method for real-time detection of inorganic pyrophosphatase (PPase) (EC 3.6.1.1) activity has been developed. The method is based on PPase-induced activation of the firefly luciferase activity in the presence of inorganic ...

Heat stress and wounding response in expression and RNAi impact on Arabidopsis thaliana soluble pyrophosphatase isoforms [PDF]

, 2009
Mature plants are assumed to lack cytoplasmic soluble pyrophosphatase activity and vacuolar membrane-bound proton-pumping pyrophosphatase is generally accepted as the sole enzyme responsible for the removal of pyrophosphate accumulated in the ...

Study of phosphorylation of inorganic pyrophosphatase from Streptococcus pneumoniae

, 2010
The human patogen Streptococcus pneumoniae encodes a single copy of eukaryotic-like Ser/Thr protein kinase StkP. StkP regulates virulence, competence, stress resistence, gene expression and plays a role in the regulation of cell division cycle.

Identification of an Arabidopsis inorganic pyrophosphatase capable of being imported into chloroplasts

, 2004
An Arabidopsis cDNA coding for a previously uncharacterized isoform of inorganic pyrophosphatase was isolated. It was used to complement an E. coli mutant, demonstrating that it coded for an active enzyme.
