Abstract:

The substituted cysteine accessibility approach, combined with chemical modification using membrane-impermeant alkylating reagents, was used to identify functionally important structural elements of the rat type IIa Na+/Pi cotransporter protein. Single point mutants with different amino acids replaced by cysteines were made and the constructs expressed in Xenopus oocytes were tested for function by electrophysiology. Of the 15 mutants with substituted cysteines located at or near predicted membrane-spanning domains and associated linker regions, 6 displayed measurable transport function compar

Abstract:

AlkB is a bacterial Fe(II)– and 2-oxoglutarate–dependent dioxygenase that repairs a wide range of alkylated nucleobases in DNA and RNA as part of the adaptive response to exogenous nucleic acid–alkylating agents. Although there has been longstanding interest in the structure and specificity of Escherichia coli AlkB and its homologs, difficulties in assaying their repair activities have limited our understanding of their substrate specificities and kinetic mechanisms. Here, we used quantitative kinetic approaches to determine the transient kinetics of recognition and repair of alkylated DNA by

Abstract:

Through the benzene alkylation experiments with long chain olefin over solid acid catalysts activated at different temperature in the fixed-bed reactor, the kinetics of alkylation reaction and the deactivation kinetics of catalyst were established. The results showed that the activity and stability of catalyst decreased with increasing the activation temperature of catalysts. The reaction rate constant (k) and the deactivation rate constant (kd) of catalyst in kinetic models were also estimated through the optimization method, respectively. The acidity of catalyst was characterized by ammonia

Abstract:

The benzene alkylation with long chain olefin over solid acid catalyst in the fixed-bed reactor was carried out under near critical conditions. The kinetic model of alkylation correlated with external diffusion and yield model of products were determined, and the model parameters, such as, the external diffusion factor, olefin conversion rate constant and the rate constant forming three products, were estimated. The statistical analysis showed the kinetic model had the higher simulation precision. Compared with the catalyst with 12~16 mesh (Cat-2), the activity and selectivity of linear alkyl

Abstract:

ABSTRACT The surface (SU) and transmembrane (TM) subunits of Moloney murine leukemia virus (Mo-MLV) Env are disulfide linked. The linking cysteine in SU is part of a conserved CXXC motif in which the other cysteine carries a free thiol. Recently, we showed that receptor binding activates its free thiol to isomerize the intersubunit disulfide bond into a disulfide within the motif instead (M. Wallin, M. Ekström and H. Garoff, EMBO J. 23:54-65, 2004). This facilitated SU dissociation and activation of TM for membrane fusion. The evidence was mainly based on the finding that alkylation of the CX

Abstract:

Alkylation of p-quinones with allylic and benzylic esters is achieved by using a strong Lewis acid as the catalyst. This transformation likely follows an unusual redox chain mechanism. In this mechanism, quinone undergoes a sequence of reactions: it is reduced to hydroquinone (HQ), functionalized in a Lewis acid-catalyzed Friedel–Crafts alkylation, and then oxidized back to quinone. The last step is concurrent with the first step of a second quinone molecule, which is reduced to new HQ and functionalized, and thus propagates the redox chain reaction. The autoinitiation mechanism of the redox

The specific activities towards the different enantiomers of TSO (trans-stilbene oxide) as substrate were 43 and 3 μmol·min−1·mg−1 with the R,R- or S,S-isomers respectively. The enzyme was, however, enantioselective in favour of the S,S enantiomer due to a lower Km value.

Abstract:

2'-Chloroacetophenones react with carbon disulfide in the presence of sodium hydride to form 4-hydroxydithiocoumarin anions. Kinetic protonation provides the 4-hydroxydithiocoumarins which can be tautomerized to 2-mercapto-1-thiochromones by treatment with strong acid. � Both tautomers are quite stable and do not readily interconvert. Alkylation of either 4-hydroxydithiocoumarin or 2-mercapto-1-thiochromone provides S-alkyl derivatives exclusively while acylation with acid anhydrides gives mixtures of O- and S-acyl products. Oxidation with sodium perborate yields the exocyclic monosulfoxide wh

Abstract:

This paper deals with alkylation of benzene with propylene to produce cumene by Suspension Catalytic Distillation (SCD) which, as a new technology of process intensification, has been developed from traditional catalytic distillation. In this SCD process, the supported heteropolyacid catalysts are suspended inside the liquid phase on the column tray and flow with them, while in traditional catalytic distillation the catalyst pellets are generally fixed somewhere inside the column. SCD processes have been investigated for alkylation reaction of benzene with olefins in laboratorial scale. A pilo

Abstract:

The production process of ethyl benzene through the alkylation reaction between ethylene and benzene is a crucial stage in the petrochemical industry, especially as the main raw material in the synthesis of styrene. The development and optimization of this process are important to increase reaction efficiency, reduce production costs, and minimize environmental impacts. This study aims to optimize the operating parameters of the alkylation reactor in order to obtain high ethylene conversion and maximum selectivity to ethyl benzene. The methods used include kinetic reaction modeling, process si
