| + | DNA polymerase beta (pol beta) lyase removal of 5'-deoxyribose phosphate (5'-dRP) from base excision repair (BER) intermediates is critical in mammalian BER involving the abasic site. We found that pol beta also removes 5'-adenylated dRP from BER intermediates after abortive ligation. The crystal structure of a human pol beta-DNA complex showed the 5'-AMP-dRP group positioned in the lyase active site. Pol beta expression rescued methyl methanesulfonate sensitivity in aprataxin (hnt3)- and FEN1 (rad27)-deficient yeast. | ||
