| Method |
Poly(A) polymerase from yeast was prepared. One unit of enzyme is the amount that incorporates 1 nmol of ATP (as AMP) into an acid insoluble form in 1 min at 37 °C. After incubation at 30 degrees or 37 degrees, the reaction mixtures were analyzed by TLC or HPLC |
| Comments |
As value>1, this is a positively cooperative reaction: Once one ligand molecule is bound to the enzyme, its affinity for other ligand molecules increases. |
