Steady-State Kinetics of Mouse DNA Polymerase α

Abstract

Steady-state kinetic studies of DNA polymerase α purified from mouse myeloma MOPC104E cells have been carried out. The results of initial velocity analysis with or without sodium pyrophosphate, a product inhibitor, indicated that the reaction mechanism of this enzyme can be categorized as an ordered Bi Bi type where the concentration of the ternary complex is very low.
