The Kinetics of Enzyme Mixtures
Even purified enzyme preparations are often heterogeneous. For example, preparations of aspartate aminotransferase or cytochrome oxidase can consist of several different forms of the enzyme. For this reason we consider how different the kinetics of the reactions catalysed by a mixture of forms of an enzyme must be to provide some indication of the characteristics of the species present. Based...

متن کاملImplications of enzyme kinetics.
Of the many examples of oscillatory kinetic behaviour known, several are briefly reviewed, including those of glycolysis, the peroxidase-oxidase reaction and oscillations in cellular calcium concentration. It is shown that simple mathematical models employing allosteric rate laws are sufficient to explain the instability of the steady state and the appearance of sustained oscillations. The cAMP...
متن کاملEnzyme kinetics at high enzyme concentration.
We re-visit previous analyses of the classical Michaelis-Menten substrate-enzyme reaction and, with the aid of the reverse quasi-steady-state assumption, we challenge the approximation d[C]/dt approximately 0 for the basic enzyme reaction at high enzyme concentration. For the first time, an approximate solution for the concentrations of the reactants uniformly valid in time is reported. Numeric...
متن کاملWilliam Palmer
of crime ! He fell by the hand of a friend and boon companion. Six months after, on the 27th of May, 1856, providentially for the ends of justice and the interests of society, the perpetrator of this foul murder was convicted and sentenced to execution; and, on the 14th of last month, he, in the presence of 50,000 persons, suffered an ignominious death upon the scaffold. We might well leave him...
