DNA polymerase beta: analysis of the contributions of tyrosine-271 and asparagine-279 to substrate specificity and fidelity of DNA replication by pre-steady-state kinetics.

DNA polymerase beta (pol beta) from rat brain, overexpressed in Escherichia coli, was used as a model to study the factors responsible for substrate specificity [kpol, Kd(app) and kpol/Kd(app)] and fidelity during DNA synthesis. The roles of two active-site residues, Asn-279 and Tyr-271, were examin...
