 1-185 9.59e-73

N-terminal domain of metazoan Nei-like glycosylase 2 (NEIL2); This family contains the N-terminal domain of the metazoan protein Neil2. It belongs to the FpgNei_N, [N-terminal domain of Fpg (formamidopyrimidine-DNA glycosylase, MutM)_Nei (endonuclease VIII)] domain superfamily. DNA glycosylases maintain genome integrity by recognizing base lesions created by ionizing radiation, alkylating or oxidizing agents, and endogenous reactive oxygen species. They initiate the base-excision repair process, which is completed with the help of enzymes such as phosphodiesterases, AP endonucleases, DNA polymerases and DNA ligases. DNA glycosylases cleave the N-glycosyl bond between the sugar and the damaged base, creating an AP (apurinic/apyrimidinic) site. Most FpgNei DNA glycosylases use their N-terminal proline residue as the key catalytic nucleophile, and the reaction proceeds via a Schiff base intermediate. NEIL2 repairs 5-hydroxyuracil (5-OHU) and other oxidized derivatives of cytosine, but it shows preference for DNA bubble structures. In addition to this MeNeil2_N domain, NEIL2 contains a helix-two turn-helix (H2TH) domain and a characteristic CHCC zinc finger motif. Neil2 is one of three homologs found in eukaryotes.

DNA-formamidopyrimidine glycosylase; All proteins in the FPG family with known functions are FAPY-DNA glycosylases that function in base excision repair. Homologous to endonuclease VIII (nei). This family is based on the phylogenomic analysis of JA Eisen (1999, Ph.D. Thesis, Stanford University). [DNA metabolism, DNA replication, recombination, and repair]

 2-179 2.75e-10

N-terminal domain of Fpg (formamidopyrimidine-DNA glycosylase, MutM)_Nei (endonuclease VIII) base-excision repair DNA glycosylases; DNA glycosylases maintain genome integrity by recognizing base lesions created by ionizing radiation, alkylating or oxidizing agents, and endogenous reactive oxygen species. These enzymes initiate the base-excision repair process, which is completed with the help of enzymes such as phosphodiesterases, AP endonucleases, DNA polymerases and DNA ligases. DNA glycolsylases cleave the N-glycosyl bond between the sugar and the damaged base, creating an AP (apurinic/apyrimidinic) site. The FpgNei DNA glycosylases represent one of the two structural superfamilies of DNA glycosylases that recognize oxidized bases (the other is the HTH-GPD superfamily exemplified by Escherichia coli Nth). Most FpgNei DNA glycosylases use their N-terminal proline residue as the key catalytic nucleophile, and the reaction proceeds via a Schiff base intermediate. One exception is mouse Nei-like glycosylase 3 (Neil3) which forms a Schiff base intermediate via its N-terminal valine. In addition to this FpgNei_N domain, FpgNei proteins have a helix-two-turn-helix (H2TH) domain and a zinc (or zincless)-finger motif which also contribute residues to the active site. FpgNei DNA glycosylases have a broad substrate specificity. They are bifunctional, in addition to the glycosylase (recognition) activity, they have a lyase (cleaving) activity on the phosphodiester backbone of the DNA at the AP site. This superfamily includes eukaryotic, bacterial, and viral proteins.

Uncharacterized bacterial subgroup of the N-terminal domain of Fpg (formamidopyrimidine-DNA glycosylase, MutM)_Nei (endonuclease VIII) base-excision repair DNA glycosylases; This family is an uncharacterized bacterial subgroup of the FpgNei_N domain superfamily. DNA glycosylases maintain genome integrity by recognizing base lesions created by ionizing radiation, alkylating or oxidizing agents, and endogenous reactive oxygen species. They initiate the base-excision repair process, which is completed with the help of enzymes such as phosphodiesterases, AP endonucleases, DNA polymerases and DNA ligases. DNA glycosylases cleave the N-glycosyl bond between the sugar and the damaged base, creating an AP (apurinic/apyrimidinic) site. Most FpgNei DNA glycosylases use their N-terminal proline residue as the key catalytic nucleophile, and the reaction proceeds via a Schiff base intermediate. This N-terminal proline is conserved in this family. Escherichia coli Fpg prefers 8-oxo-7,8-dihydroguanine (8-oxoG) and oxidized purines, and Escherichia coli Nei recognizes oxidized pyrimidines. However, neither Escherichia coli Fpg or Nei belong to this family. In addition to this BaFpgNei_N_2 domain, enzymes belonging to this family contain a helix-two turn-helix (H2TH) domain. Most also contain a zinc-finger motif.
