Method Pre-steady-state kinetic analysis was used to compare the catalytic properties of DNA polymerase beta (Pol beta) for single-base gap-filling and regular duplex DNA synthesis. The rate of polymerization (kpol) and the apparent equilibrium dissociation constant of dNTP (Kd) were determined with single-nucleotide gapped DNA substrates for all four possible correct base pairs and twelve possible incorrect base pairs, and the results were compared with those obtained previously with non-gapped primer/template duplex DNA substrates.
