Comparative Biochemistry and Physiology, 1962
THE determination of mechanisms of enzyme action is among the great problems of modern chemistry (Boyer e t a l . , 1960; Boyer, 1960; Westheimer, 1959). Although not one enzymatic process is today understood, and although no model system has achieved catalytic activity comparable to that of the corresponding enzyme, considerable progress has been made

Diffusion-controlled enzymes are characterized by second-order rate constants in the range 10(8)-10(10) M(-1)s(-1). These values are at the upper end of the observed rates of many enzyme-substrate reactions and have been predicted by theoretical studies on bimolecular reaction in solution.

Hybrid enzymes: manipulating enzyme design
Trends in Biotechnology, 1998Hybrid enzymes are engineered to contain elements of two or more enzymes. Hybrid-enzyme approaches, by taking advantage of the vast array of enzymatic properties that nature has evolved, as well as the strategies that nature has used to evolve them, are becoming an increasingly important avenue for obtaining novel enzymes with desired activities and ...

Essays in Biochemistry, 1999
There are many molybdenum-containing enzymes distributed throughout the biosphere. The availability of molybdenum to biological systems is due to the high water solubility of oxidized forms of the metal. Molybdenum enzymes can be grouped on the basis of the structure of the metal centre.

Enzymes Indigenous to Milk | Other Enzymes
2011Several enzymes have been identified or purified from mammalian milk in trace amounts. Some of these enzymes have specific and established functions in the mammary gland, in milk, or in the newborn (e.g., catalase, lysozyme, lactate dehydrogenase). Their activities in milk may reflect physiological changes or a pathological state of the mammary gland ...

An Artificial Acyl-Enzyme and An Artificial Enzyme
Journal of Inclusion Phenomena, 1984The synthesis and characterization of an artificial acyl-enzyme intermediate of chymotrypsin, and an artificial enzyme, chymotrypsin, are described. They both contain the same three catalytic groups, an imidazolyl group, a hydroxyl group, and a carboxylate ion.

Enzyme kinetics in relation to enzyme inhibitors
Biochemical Pharmacology, 1973Abstract A Large number of pharmacologically important compounds have been found to act as enzyme inhibitors and a kinetic study of the inhibitory process can provide important information on the potency of the compound and on its mode of interaction with the enzyme.
