Escherichia coli exonuclease III (ExoIII) and Neisseria meningitides NExo-like subfamily of ...
69-213 2.59e-07

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.

Endonuclease domain (L1-EN) of the non-LTR retrotransposon LINE-1 (L1), and related domains; This family contains the endonuclease domain (L1-EN) of the non-LTR retrotransposon LINE-1 (L1), and related domains, including the endonuclease of Xenopus laevis Tx1. 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. 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.

Escherichia coli exonuclease III (ExoIII)-like apurinic/apyrimidinic (AP) endonucleases; The ExoIII family AP endonucleases 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, which is then followed by the coordinated actions of DNA polymerase, deoxyribose phosphatase, and DNA ligase. If left unrepaired, AP sites block DNA replication, which have both mutagenic and cytotoxic effects. AP endonucleases can carry out a wide range 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 efficiences. Many organisms have two functional AP endonucleases, for example, APE1/Ref-1 and Ape2 in humans, Apn1 and Apn2 in bakers yeast, Nape and NExo in Neisseria meningitides, and exonuclease III (ExoIII) and endonuclease IV (EndoIV) in Escherichia coli. Usually, one of the two is the dominant AP endonuclease, the other has weak AP endonuclease activity, but exhibits strong 3'-5' exonuclease, 3'-deoxyribose phosphodiesterase, and 3'-phosphatase activities. Class II AP endonucleases have been classified into two families, designated ExoIII and EndoIV, based on their homology to the Escherichia coli enzymes. This family contains the ExoIII family; the EndoIV family belongs to a different superfamily.
