A novel enzyme system, myo-inositol-1-phosphate dehydrogenase, has been isolated from germinating mung bean seeds. The dehydrogenation and cleavage of myo-inositol 1-phosphate by this enzyme leads to the synthesis of a pentose phosphate which appears to be ribulose 5-phosphate. The pH optimum of the enzyme is 8.6; NAD+ is required as coenzyme and no other nucleotides can replace NAD+. Mono- or ...

Coccidiosis is likely the most costly disease threat to global poultry production and prevention of coccidiosis is essential in order to maintain intestinal integrity and the efficient absorption of nutrients in the chicken. Narasin is an ionophore anticoccidial. Ionophores transport cations such as sodium across the pellicle membrane of sporozoites of coccidia, resulting in a lethal osmotic im...

Mammalian innate immunity stimulates antigen-specific immune responses and acts to control infection prior to the onset of adaptive immunity. Some bacterial pathogens replicate within the host cell and are therefore sheltered from some protective aspects of innate immunity such as complement. Here we focus on mechanisms of innate intracellular resistance encountered by bacterial pathogens and h...

The de-N-acetylation of N-acetyl-D-glucosaminylphosphatidylinositol (GlcNAc-PI) is the second step of mammalian and trypanosomal glycosylphosphatidylinositol biosynthesis. Glycosylphosphatidylinositol biosynthesis is essential for Trypanosoma brucei, the causative agent of African sleeping sickness, and GlcNAc-PI de-N-acetylase has previously been validated as a drug target. Inhibition of the t...

The enzymatic activity of citrate synthase from pig heart can be inhibited by various ions. The order of inhibitory effect of monovalent cations is Li+ > K+ > Na+ > Cs+ and that of anions is SCN> Cl> tartrate. Divalent cations such as Ca2+ and Mg2+ are much more effective than monovalent cations, but thiocyanate is as effective as divalent cations. ATP is also a potent inhibitor, but dATP has n...

Large libraries pose signi€cant challenges to static points-to analysis. A popular solution is to have a human analyst provide points-to speci€cations that summarize relevant behaviors of library code, which can substantially improve precision and scalability, and furthermore handle missing code such as native code. We propose Atlas, a tool that automatically infers points-to speci€cations. Atl...

Synthesis and cation selectivity of 25, 27, dipropoxy-26, 28, Di-propoxy 5, 11, 17, 23, ptert-butyl Calix[4]arene are studied in acetonitrile solution. The stability constants of differentcomplexes of Calixarene (as a ligand) with alkali metal cations are determined at 25 °C by usingspectrophotometric technique.On the basis of calculations, complexation of Calixarene with Cs+and Li+ are more fa...

First, crystalline NiFe2O4 powder was synthesized on a nanoscale dimension by a simple one-step coprecipitationchemical route, and then used to produce activated carbon/NiFe2O4 nanocomposite. Thestructure and morphology of the as-prepared composite was characterized by X-ray diffraction (XRD)pattern, transmission electron microscope (TEM) and Fourier transform infrared (FT-IR)...

What are Cation Exchange and Cation Exchange Capacity? Soil clay minerals and organic matter tend to be negatively charged, thus attracting positively charged ions (cations) on their surfaces by electrostatic forces. As a result, the cations remain within the soil root zone and are not easily lost through leaching. The adsorbed cations may easily exchange with other cations in the soil solution...
