Monofunctional vs. bifunctional glycosylases. There are two main classes of glycosylases: monofunctional and bifunctional.

Mammalian cells require non-homologous end joining (NHEJ) for the efficient repair of chromosomal DNA double-strand breaks. A key feature of biological sources of strand breaks is associated nucleotide damage, including base loss (abasic or apurinic/apyrimidinic (AP) sites). At single-strand breaks, 5'-terminal abasic sites are excised by the 5'-deoxyribose-5-phosphate (5'-dRP) lyase activity Kevin G. Pinz, Daniel F. Bogenhagen By virtue of its binding to AP sites, PARP-1 could be poised for its role in base excision repair, pending DNA strand incision by APE1 or the 5′-dRP/AP lyase activity in PARP-1. The capacity of human poly(ADP-ribose) polymerase-1 (PARP-1) to interact with intact apurinic/apyrimidinic (AP) sites in DNA has been demonstrated. The Ku AP lyase activity is also strongly suppressed by as little as two paired bases 5′ of the abasic site. Importantly, in vitro end joining experiments show that abasic sites significantly embedded in double-stranded DNA do not block the NHEJ ligation step.

In enzymology, DNA-(apurinic or apyrimidinic site) lyase, also referred to as DNA-(apurinic or apyrimidinic site) 5'-phosphomonoester-lyase (systematic name) or DNA AP lyase (EC 4.2.99.18) is a class of enzyme that catalyzes the chemical reaction of the cleavage of the C 3'-O-P bond 3' from the apurinic or apyrimidinic site in DNA via beta-elimination reaction, leaving a 3'-terminal In enzymology, DNA-(apurinic or apyrimidinic site) lyase, also referred to as DNA-(apurinic or apyrimidinic site) 5'-phosphomonoester-lyase(systematic name) or DNA AP lyase(EC4.2.99.18) is a class of enzymethat catalyzesthe chemical reactionof the cleavage of the C3'-O-P bond 3' from the apurinic or apyrimidinic site in DNA via beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate. Function i Bifunctional DNA glycosylase/lyase, which excises 5-methylcytosine (5-meC) and 5-hydroxymethylcytosine (5-hmeC), leaving an apyrimidinic (AP) site that is subsequently incised by the lyase activity (PubMed: 25240767).

AP Endonucleases. We distinguish AP endonucleases as enzymes that activate water to mediate cleavage of the phosphodiester bonds, and produce a nick with 5′-deoxyribose-5-phosphate. This contrasts with the glycosylase/lyases that produce nicks with the unsaturated abasic derivative attached to a 3′ end ( Figure 2 ).

NEIL3 has AP lyase activity on ssDNA. Glycosylitic release of oxidized bases by the Fpg‐Nei glycosylase family is followed by the β–δ elimination reaction of the associated AP lyase, resulting in … 2010-04-11 Excision of AP sites near DSBs by a 5'dRP/AP lyase is thus critical for efficient and accurate resolution of such ends by cellular NHEJ (Figure 1a). Consistent with other studies 14 , 15 (reviewed in 16 ) an alternative to NHEJ (Alt-NHEJ) allows for significant joining of undamaged ends in Ku70 deficient cells ( Figure 1d , columns 1 and 2, 7 and 8).

Base Excision Repair - an overview ScienceDirect Topics

2000-04-28 DNA-(Apurinic or Apyrimidinic Site) Lyase DNA-Formamidopyrimidine Glycosylase Deoxyguanosine / analogs & derivatives* A new class of nucleic acid substrates for AP endonucleases and members of the glycosylase/lyase family of enzymes is described. Representatives of each family, the enzymes Nfo and fpg, respectively, cleave nucleic acid backbones at positions in which a base has been replaced by a linker to which a variety of label moieties may be attached. In biochemistry, a lyase is an enzyme that catalyzes the breaking (an "elimination" reaction) of various chemical bonds by means other than hydrolysis (a "substitution" reaction) and oxidation, often forming a new double bond or a new ring structure. The reverse reaction is also possible (called a "Michael addition").For example, an enzyme that catalyzed this reaction would be a lyase: We conducted a biochemical characterization of the AP lyase activities of Ntg1p and Ntg2p via a series of kinetic experiments. Such studies were designed to determine if Ntg1p and Ntg2p prefer speci®c bases located opposite abasic sites and whether these lesions are processed with a catalytic ef®ciency similar to Apn1p, the major hydrolytic AP endo-nuclease of yeast.

Has little specificity for the base opposite oxoG (PubMed:10521423). Monofunctional vs. bifunctional glycosylases. There are two main classes of glycosylases: monofunctional and bifunctional. Monofunctional glycosylases have only glycosylase activity, whereas bifunctional glycosylases also possess AP lyase activity that permits them to cut the phosphodiester bond of DNA, creating a single-strand break without the need for an AP endonuclease. Lyaser är en enzymklass vars uppgift är att katalysera spjälkningsreaktioner.
