Rat DNA polymerase beta gene can join in excision repair of Escherichia coli.

Abstract:

Though DNA polymerase I (poll) of Escherichia (E.) coli is understood to play a role in repair synthesis of excision repair, it is still obscure whether DNA polymerase beta (pol beta) plays a similar role in eukaryotic cells. To estimate the role of pol beta in excision repair processes, we inserted the rat pol beta gene into several mutant E. coli defective in a diverse set of enzymatic activities of poll. UV resistance was seen only when the 5'----3' exonuclease (exo) activity of poll molecules remained. Therefore it is suggested that 5'----3' exo activity as well as pol beta activity are essential for repair synthesis of excision repair in eukaryotic cells.
