Steady-state parameters of an enzyme from n.m.r. spin transfer with thermal variation
1Department of Biochemistry, University of Sydney, N.S.W., Australia.
Abstract:
N.m.r. spin-exchange analysis of enzymic reactions at chemical equilibrium is akin to radioactive-tracer-exchange analysis; unidirectional flux rates are obtained for the overall reaction. These data, by themselves, are not sufficient to define the values of all the individual rate constants or steady-state parameters. However, it is shown that, by measuring the dependence of the exchange rate constants on solute concentration and temperature, the individual rate constants, and hence the steady-state parameters, can be obtained for a simple enzyme system.

In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
