Enzymatic applications

For this goal, more fundamental mechanistic studies of redox processes at BDD electrodes will be necessary. With chemically and mechanically more stable BDD/support combinations, preparative organic synthesis and enzymatic applications will conquer the field of research and will bring chemical innovation in a short time to application. [Pg.139]

For most screening procedures and bioindustrial enzymatic applications, it is essential that adequate amounts of enzyme can be produced through heterologous expression in E. coli or similar strains of bacteria. Unfortunately, difference between eukaryotic and prokaryotic protein folding means that enzymes that express well in eukaryotes may not express well in prokaryotes, because of different folding chaperones, and so on. Thus, there is often a pressing need to improve enzyme solubility and expression before enzymes can be used. [Pg.740]

Chapter 8 focuses on the properties of ionic liquids/supercritical carbon dioxide biphasic systems for enzymatic applications. [Pg.513]

Many complex systems have been spread on liquid interfaces for a variety of reasons. We begin this chapter with a discussion of the behavior of synthetic polymers at the liquid-air interface. Most of these systems are linear macromolecules however, rigid-rod polymers and more complex structures are of interest for potential optoelectronic applications. Biological macromolecules are spread at the liquid-vapor interface to fabricate sensors and other biomedical devices. In addition, the study of proteins at the air-water interface yields important information on enzymatic recognition, and membrane protein behavior. We touch on other biological systems, namely, phospholipids and cholesterol monolayers. These systems are so widely and routinely studied these days that they were also mentioned in some detail in Chapter IV. The closely related matter of bilayers and vesicles is also briefly addressed. [Pg.537]

Flow injection analysis has also found numerous applications in the analysis of clinical samples, using both enzymatic and nonenzymatic methods. A list of selected examples is given in Table 13.3. [Pg.656]

Enzymes not only produce characteristic and desirable flavor (79) but also cause flavor deterioration (80,81) (see Enzyme Applications, Industrial). The latter enzyme types must be inactivated in order to stabilize and preserve a food. Freezing depresses enzymatic action. A more complete elimination of enzymatic action is accompHshed by pasteurization. [Pg.17]

Chemical lysis, or solubilization of the cell wall, is typically carried out using detergents such as Triton X-100, or the chaotropes urea, and guanidine hydrochloride. This approach does have the disadvantage that it can lead to some denaturation or degradation of the produci. While favored for laboratory cell disruption, these methods are not typically used at the larger scales. Enzymatic destruction of the cell walls is also possible, and as more economical routes to the development of appropriate enzymes are developed, this approach could find industrial application. Again, the removal of these additives is an issue. [Pg.2059]

This chapter presents the implementaiton and applicable of a QM-MM method for studying enzyme-catalyzed reactions. The application of QM-MM methods to study solution-phase reactions has been reviewed elsewhere [44]. Similiarly, empirical valence bond methods, which have been successfully applied to studying enzymatic reactions by Warshel and coworkers [19,45], are not covered in this chapter. [Pg.222]

CS indicated that the enolate of acetyl-CoA is significantly more stable than the enol or a proton-sharing enolic form and thus do not support the proposal that a low barrier hydrogen bond is involved in catalysis in CS. This study demonstrates the practial application of high level QM-MM studies to the elucidation of mechanistic details of an enzymatic reaction that are otherwise unclear. [Pg.234]

Mention should also be made here of the extensive use of poly(vinyl alcohol) in potentially biodegradable applications. At appropriate hydroxyl contents these polymers will dissolve in water (see Chapter 14) and can apparently be conveniently washed away after use as a water-soluble packaging. Biodegradation does, however, appear to be slow and first requires an oxidative step involving enzymatic attack to a ketone such as polyenolketone, which then biodegrades more rapidly. [Pg.882]

Gravimetric, photometric, chromatographic, enzymatic, and microbiological methods for the determination of amino acids are reviewed and discussed. Marked advances have been made during the present decade in methods applicable to the determination of amino acids, and with the development of new analytical methods it should soon be possible to determine all the amino acids of biological importance with a degree of accuracy sufficient for practical as well as many theoretical purposes. [Pg.13]
