Exploiting Enzymes: Technology and Applicationse of enzyme preparations in meat tenderizing and starch hydrolysis. From the very beginning, commercial enzyme applications have largely belonged to a group of hydrolytic reactions. But a few oxidative enzymes were also exploited. While this trend holds even today, examples of designer enzymes and c

On Enzyme Nomenclature and Classification carry the suffix “-ase” as recommended for all enzyme names by Duclaux in 1898. Proteolytic enzymes are a significant exception to this generally accepted norm. Some of them have retained the older tradition of usually ending with “-in,” for example, trypsin, chymotrypsin, papain, and subtilisin.

Hallmarks of an Enzyme Catalystrrier can be overcome by employing a catalyst. Reactions with a thermodynamic barrier (uphill, endergonic reactions) require provision of energy (such as ATP hydrolysis) in addition to a catalyst. Regardless of the nature of barriers faced, greater than 99% of all the reactions occurring in biologic

Chemical Kinetics: Fundamentalsabolism is made possible through enzymes. Whether enzyme catalyzed or not, a chemical reaction is best understood through fundamental tenets of chemical kinetics. Therefore an overview of this field is provided here.

ES Complex and Pre-steady-state Kinetics in intimate contact with their substrates (reactants). Interaction of an enzyme (E) and its cognate substrate (S) begins the moment the two come together through diffusion. Specific interactions and binding result in the formation of enzyme-substrate (ES) complex. All the transition state(s) and in

Principles of Enzyme Assaysliable measure of the progress of an enzyme-catalyzed reaction is first and foremost requirement. Like with any other chemical reaction, progress of an enzyme-catalyzed reaction can be monitored either by the product formed (.[P]/.t) or by the substrate consumed (−.[A]/.t). The two rates are of cour
