Escherichia coli exonuclease III (ExoIII) and Neisseria meningitides NExo-like subfamily of the ExoIII family purinic/apyrimidinic (AP) endonucleases; This subfamily includes Escherichia coli ExoIII, Neisseria meningitides NExo,and related proteins. These are ExoIII family AP endonucleases and they belong to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds. AP endonucleases participate in the DNA base excision repair (BER) pathway. AP sites are one of the most common lesions in cellular DNA. During BER, the damaged DNA is first recognized by DNA glycosylase. AP endonucleases then catalyze the hydrolytic cleavage of the phosphodiester bond 5' to the AP site, and this is followed by the coordinated actions of DNA polymerase, deoxyribose phosphatase, and DNA ligase. If left unrepaired, AP sites block DNA replication, and have both mutagenic and cytotoxic effects. AP endonucleases can carry out a variety of excision and incision reactions on DNA, including 3'-5' exonuclease, 3'-deoxyribose phosphodiesterase, 3'-phosphatase, and occasionally, nonspecific DNase activities. Different AP endonuclease enzymes catalyze the different reactions with different efficiencies. Many organisms have two AP endonucleases, usually one is the dominant AP endonuclease, the other has weak AP endonuclease activity. For example, Neisseria meningitides Nape and NExo, and exonuclease III (ExoIII) and endonuclease IV (EndoIV) in Escherichia coli. NExo and ExoIII are found in this subfamily. NExo is the non-dominant AP endonuclease. It exhibits strong 3'-5' exonuclease and 3'-deoxyribose phosphodiesterase activities. Escherichia coli ExoIII is an active AP endonuclease, and in addition, it exhibits double strand (ds)-specific 3'-5' exonuclease, exonucleolytic RNase H, 3'-phosphomonoesterase and 3'-phosphodiesterase activities, all catalyzed by a single active site. Class II AP endonucleases have been classified into two families, designated ExoIII and EndoIV, based on their homology to the Escherichia coli enzymes ExoIII and endonuclease IV (EndoIV). This subfamily belongs to the ExoIII family; the EndoIV family belongs to a different superfamily. Pssm-ID: 197320 [Multi-domain] Cd Length: 254 Bit Score: 368.77 E-value: 3.95e-130

After incision at the 5'-side of a 2'-d-uridine residue by Mth212, DNA polymerase B takes over the 3'-OH terminus and carries out repair synthesis, generating a 5'-flap structure that is resolved by a 5'-flap endonuclease. Finally, DNA ligase seals the resulting nick. This U-endo activity shares the same catalytic center as its AP-endo activity, and is absent from other AP endonuclease homologues.

These retrotranspons belong to the subtype 2, L1-clade. LINES can be classified into two subtypes. Subtype 2 has two ORFs: the second (ORF2) encodes a modular protein consisting of an N-terminal apurine/apyrimidine endonuclease domain (EN), a central reverse transcriptase, and a zinc-finger-like domain at the C-terminus. LINE-1/L1 elements (full length and truncated) comprise about 17% of the human genome. This endonuclease nicks the genomic DNA at the consensus target sequence 5'TTTT-AA3' producing a ribose 3'-hydroxyl end as a primer for reverse transcription of associated template RNA. This subgroup also includes the endonuclease of Xenopus laevis Tx1, another member of the L1-clade.

Phosphodiesterase domain of human TDP2, a 5'-tyrosyl DNA phosphodiesterase, and related domains; Human TDP2, also known as TTRAP (TRAF/TNFR-associated factors, and tumor necrosis factor receptor/TNFR-associated protein), is a 5'-tyrosyl DNA phosphodiesterase. It is required for the efficient repair of topoisomerase II-induced DNA double strand breaks. The topoisomerase is covalently linked by a phosphotyrosyl bond to the 5'-terminus of the break. TDP2 cleaves the DNA 5'-phosphodiester bond and restores 5'-phosphate termini, needed for subsequent DNA ligation, and hence repair of the break. TDP2 and 3'-tyrosyl DNA phosphodiesterase (TDP1) are complementary activities; together, they allow cells to remove trapped topoisomerase from both 3'- and 5'-DNA termini. TTRAP has been reported as being involved in apoptosis, embryonic development, and transcriptional regulation, and it may inhibit the activation of nuclear factor-kB. This family belongs to the large EEP (exonuclease/endonuclease/phosphatase) superfamily that contains functionally diverse enzymes that share a common catalytic mechanism of cleaving phosphodiester bonds.
