A DNA oligomer containing 2,2,4-triamino-5(2H)-oxazolone is incised by human NEIL1 and NTH1.
Mutation Research 2012 June 2
The nucleobase derivative, 2,2,4-triamino-5(2H)-oxazolone (Oz), is an oxidation product of guanine or of 8-oxo-7,8-dihydroguanine that causes G-to-C transversions in DNA. Human NEIL1 (hNEIL1) and NTH1 (hNTH1) are homologues of two prokaryotic base excision repair enzymes, FPG/NEI and NTH, respectively. Here, we demonstrated that hNEIL1 and hNTH1 cleave Oz sites as efficiently as 5-hydroxyuracil sites. Thus, hNEIL1 and hNTH1 can repair Oz lesions. Furthermore, the nicking activities of these enzymes are largely independent of nucleobases opposite Oz; this finding indicates that removing Oz from Oz:G and Oz:A base pairs might cause an increase in the rate of point mutations in human cells.
