The structure of a protein-protein interaction, its affinity and thermodynamic characteristics depict a 'frozen' state of a complex. This picture ignores the kinetic nature of complex formation and dissociation, which are of major biological and biophysical interest. This review highlights recent advances in deciphering the kinetic pathway of protein-protein complexation, the nature of the enco...

recently, extracts from various parts of a. occidentale had been massively investigated in themanagement and treatment of various ailments which include but not limited to diabetes, malaria,yellow fever as well as diarrhea. stem bark of anacardium occidentale was extracted with water andethanol. antioxidant activities of the extracts were using dpph. for estimation of effectivediffusivity, math...

in this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3he atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. to perform the calculations, we have considered the kinetic term, and coulomb interaction between the particles in our hamiltonian. the calculated properties are free ener...

The corrosion inhibition and adsorption (CIA) performance of the aqueous extracts of Aaronsohnia pubescens aerial parts (Odorized aqueous extract (OE) and Deodorized aqueous extract (DE)) on the corrosion mild steel (MS) in 1M hydrochloric acid were evaluated. It is based on the weight loss (WL) analysis, kinetic and thermodynamic parameters, and electrochemical methods both stationary (Potenti...

The reactions of propenyl magnesium halides with ethylene were studied using ab initio calculations. The structure of the transition state and the ground state were evaluated and obtained the structural properties, theoretical thermodynamic and kinetic data i.e. rate constants of the reactions. The methods used for calculations are RHF, B3LYP and MP2 with 6-31G* b...

Introduction: Nisin is a bacteriocin produced by Streptococcus and Lactococcus species has antimicrobial activity against other bacteria. omits the need to use chemical preservatives in food due its biological preserving properties. Methods: In present vitro study, we investigated nisin interaction with bovine serum albumin (BSA) using fluorescence spectroscopy surface plasmon resonance (SPR) a...

Direct observation and structural characterization of a kinetic product and a thermodynamic product for complexes with an NO2S2 macrocycle (L) are reported. L reacts with copper(I) iodide to give a mononuclear complex [Cu(L)]2(Cu2I4)·2CH2Cl2 (1), featuring three separate units. When cadmium(II) iodide was reacted with L, an anion-coordinated complex [Cd(L)I]2(Cd2I6)·4CH3CN (2) with a needle-typ...

The effects of adsorbate lateral interactions on the kinetics of surface diffusion and desorption are studied by means of kinetic and thermodynamic Monte Carlo simulations. This study is motivated by recent diffusion and desorption experiments on the NH3/Re~001! system, which show that the activation energies of these processes decrease ~in different fashions! with increasing surface coverage, ...
