چکیده

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 no effect. The inhibition by monoand divalent cations and ATP can be overcome by an increase in the concentration of one of the substrates, acetyl coenzyme A, but not the other, oxalacetate.

Effect of aluminum on metabolism of organic acids and chemical forms of aluminum in root tips of Eucalyptus camaldulensis Dehnh.

Eucalyptus (Eucalyptus camaldulensis) has relatively high resistance to aluminum (Al) toxicity than the various herbaceous plants and model plant species. To investigate Al-tolerance mechanism, the metabolism of organic acids and the chemical forms of Al in the target site (root tips) in Eucalyptus was investigated. To do this, 2-year old rooted cuttings of E. camaldulensis were cultivated in h...

Synthesis of 1,5 and 2,5-disubstituted tetrazoles using NiO nanoparticles and their evaluation as antimicrobial agents

Treatments of tetrazolate salts prepared in situ from various aldehyde; malononitrile and sodium azide in the presence of NiO nanoparticles with benzyl bromide gave the corresponding 1,5- and 2,‌5-disubstituted tetrazoles. Reaction of tetrazolate salts with 2,4′-dibromoacetophenone in the presence of NiO nanoparticles provided the corresponding 2,5-disubstituted derivatives as an only isomer. T...

Bacillus Amyloliquefaciens Alpha-amylase Inhibition by Organic Solvents: A Study on Methanol, Ethanol and Propanol

Alpha-amylase is widely used as an industrial enzyme, and a therapeutic target for which inhibitors are designed. Organic solvents are used to dissolve various compounds that would be studied as moderators of alpha-amylases, but they could themselves affect enzyme activity and stability. Methanol, ethanol and propanol are simple alcohols that may be commonly used to this end, and their effect h...

Effects of the Solvent and Calcination Temperature on LaFeO3 Catalysts for Methanol Oxidation

In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...
