Human AlkB homologue 1 (ABH1) exhibits DNA lyase activity at abasic sites

Bacterial AlkB and three human AlkB homologues (ABH1, ABH2, and ABH3) are Fe(2+)/2-oxoglutarate-dependent oxygenases that directly repair alkylation-damaged DNA. Here, we show that ABH1 unexpectedly has a second activity, cleaving DNA at abasic (AP) sites such as those arising spontaneously from alk...
