  Hydrolytic deamination of cytosine to uracil in cellular DNA is a major source of C-to-T transition mutations if uracil is not repaired by the DNA base excision repair (BER) pathway. Since deamination increases rapidly with temperature, hyperthermophiles, in particular, are expected to succumb to such damage. There has been only one report of crenarchaeotic BER showing strong similarities to that in most eukaryotes and bacteria for hyperthermophilic Archaea. Here we report a different type of BER performed by extract prepared from cells of the euryarchaeon Archaeoglobus fulgidus. Although immunodepletion showed that the monofunctional family 4 type of uracil-DNA glycosylase (UDG) is the principal and probably only UDG in this organism, a beta-elimination mechanism rather than a hydrolytic mechanism is employed for incision of the abasic site following uracil removal. The resulting 3' remnant is removed by efficient 3'-phosphodiesterase activity followed by single-nucleotide insertion and ligation. The finding that repair product formation is stimulated similarly by ATP and ADP in vitro raises the question of whether ADP is more important in vivo because of its higher heat stability.

  Endogenous formation of the mutagenic DNA adduct 1,N-6-ethenoadenine (epsilon A) originates from lipid peroxidation. Elevated levels of epsilon A in cancer-prone tissues suggest a role for this adduct in the development of some cancers. The base excision repair pathway has been considered the principal repair system for epsilon A lesions until recently, when it was shown that the Escherichia coli AlkB dioxygenase could directly reverse the damage. We report here kinetic analysis of the recombinant human AlkB homologue 2 (hABH2), which is able to repair epsilon A lesions in DNA. Furthermore, cation exchange chromatography of nuclear extracts from wild-type and mABH2(-/-) mice indicates that mABH2 is the principal dioxygenase for EA repair in vivo. This is further substantiated by experiments showing that hABH2, but not hABH3, is able to complement the E. coli alkB mutant with respect to its defective repair of etheno adducts. We conclude that ABH2 is active in the direct reversal of epsilon A lesions, and that ABH2, together with the alkyl-N-adenine-DNA glycosylase, which is the most effective enzyme for the repair of epsilon A, comprise the cellular defense against epsilon A lesions.
