Funkcija[uredi | uredi izvor]

AlkB protein Escherichia coli štiti od citotoksičnosti metilacijskih agenasa, popravljanjem specifičnih molekulskih lezija DNK, nastalih u jednolančanoj DNK. ALKBH2 (MIM 610602) i ALKBH3 su homolozi AlkB-a 'E. coli koji kataliziraju uklanjanje 1-metiladenina i 3-metilcitozina (Duncan et al., 2002 PubMed 12486230]).
