DNA Polymerase gamma Proteins and Enzymes

As the only DNA polymerase (pol) present in mitochondria, DNA polymerase gamma (POLG) is necessarily implicated in base excision repair processes to correct oxidative damage to the mitochondrial genome. Therefore, the ability of the catalytic subunit of human POLG has been tested to participate in uracil-provoked base excision repair reconstituted in vitro with purified components. Subsequent to actions of uracil-DNA glycosylase and apurinic/apyrimidinic endonuclease, human POLG is able to fill ...
