This textbook for complex classes in enzyme chemistry and enzyme kinetics covers the sphere of steady-state enzyme kinetics from the elemental rules inherent within the Henri equation to the expressions that describe the keep an eye on of multi-enzyme pathways. Steady-state kinetic equations are derived with using the relationship matrix technique, and an set of rules is constructed that may be carried out simply for computer-based derivation of the equations.

OVERVIEW: THE Na,K-PUMP 25 from the effect of Li + on the phosphatase activity, 35it has been postulated that there are simultaneously existing extracellular and cytoplasmic sites and that the reaction, which leads to the N a + - K + exchange, occurs with simultaneous binding of K + to the extracellular sites and of Na ÷ to the cytoplasmic sites.

However, Vmaxfor the Na ÷ + K+-dependent hydrolysis of ATP decreases in proportion to the number of ouabain molecules prebound. This shows that ouabain bound to one a,fl has no effect on Vm~ for the hydrolytic activity of another a,fl, and suggests no cooperativity between two a,fl units for hydrolysis. This agrees with the observation that a,/3 obtained by detergent dissociation of (a, 13)2has Na ÷ + K+-dependent ATPase activity. Thus, under certain conditions there is interaction between binding sites on different a,fl units which have Na+,K+-ATPase activity, but apparently there is no interaction between the units for the Na+,K+-ATPase activity.
