We recently reported that fermentable non-digestible carbohydrates including fructo-oligosaccharides (FOS) commonly elevate colonic alkaline phosphatase (ALP) activity and the expression of IAP-I, an ALP gene, in rats fed a high-fat (HF) diet, and also elevate gut mucins and modulate In order to determine the involvement of glucose-6-phosphatase in mucilage secretion by root cap cells, we have cytochemically localized the enzyme in columella and peripheral cells of root caps of Zea mays. Glucose-6-phosphatase is associated with the plasmalemma and cell wall of columella cells.
BACKGROUND
Protein tyrosine phosphatase expressed in insulin-sensitive tissues (such as liver, muscle, and adipose tissue) has a key role in the regulation of insulin signaling and pathway activation, making protein tyrosine phosphatase a promising target for the treatment of type 2 diabetes
The pool of thiamine diphosphate (TDP), available for TDP-dependent enzymes involved in the major carbohydrate metabolic pathways, is controlled by two enzyme systems that act in the opposite directions. The thiamine pyrophosphokinase (TPK) activates thiamine into TDP and the numerous phosphatases
The activity and allosteric properties of plant phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) are controlled posttranslationally by specific reversible phosphorylation of a strictly conserved serine residue near the N-terminus. This up/down-regulation of PEPC is catalyzed by a dedicated and
Effect of spermaceti oil, cod-liver oil and corn oil on the content of total, direct and indirect bilirubin, on the activity of transaminase, alkaline phosphatase and colloid resistance was studied in three animal species (rabbits, guinea-pigs and albino rats) during 120 days (90 days of
According to the conserved motifs of plant protein phosphatase 2C gene, degenerate oligonucleotides were designed. A full cDNA sequence of PP2C gene from Zea mays L. roots was cloned by RT-PCR. It was named ZmPP2C and had 936 bp. Southern blot showed that the ZmPP2C gene was a low copy in the Zea
Purple acid phosphatases (PAPs) play an important role in plant phosphorus nutrition, both by liberating phosphorus from organic sources in the soil and by modulating distribution within the plant throughout growth and development. Furthermore, members of the PAP protein family have been implicated
Acid phosphatase activity (orthophosphoric-monoester phosphohydrolase, EC 3.1.3.2) increased during the first 24 h of maize (Zea mays) seed germination. The enzyme displayed a pH optimum of 4.5-5.5. Catalytic activity in vitro displayed a linear time course (60 min) and reached its half maximum
Surfactant-like particles (SLP) are unilamellar secreted membranes associated with the process of lipid absorption and isolated previously only from the apical surface of enterocytes. In this paper, the intracellular membrane has been isolated from corn oil-fed animals, identified by its content of
ZmPP2C (AY621066) is a protein phosphatase type-2c previously isolated from roots of Zea mays (LD9002). In this study, constitutive expression of ZmPP2C in Arabidopsis thaliana under the control of the Cauliflower Mosaic Virus (CaMV) 35S promoter decreased plant tolerance to salt and drought during
In this study, the specific contribution of polyamine oxidase (PAO), a hydrogen peroxide (H2O2)-producing enzyme, to the oxidative burst induced in maize mesocotyl by the phosphatase inhibitor cantharidin was examined. For this purpose, a pharmacological approach was applied using, either in vitro
Maize is the most important crop around the world and it is highly sensitive to abiotic stress caused by drought, excessive salinity, and extreme temperature. In plants, trehalose has been widely studied for its role in plant adaptation to different abiotic stresses such as drought, high and low
Immunological and biochemical evidence has been obtained for an interaction of maize protein phosphatase 2A (PP2A) holoenzyme with tubulin. Tubulin co-purifies with maize seedling PP2A. Affinity chromatography of the maize PP2A preparation on immobilized tubulin revealed two peaks of phosphorylase
Free and bound acid phosphatase were investigated biochemically and electrophoretically in male sterile and fertile plants. Scutella at the 72-hr seedling stage and anthers with enclosed reproductive tissue at the premeiosis, meiosis, and mature developmental stages were tested. Biochemical data
