The kinetics of thermal deactivation for thermostable DNA polymerase e
nzymes were investigated by using the experimental data published else
where (Nielson et al. 1996. Strategies. 9, 7-8). The order of deactiva
tion (alpha) and the deactivation rate constants (k(d)) were determine
d for different Taq DNA polymerase enzymes and were found to be of fir
st order.
