WB analysis using 15421-1-AP. Various lysates were subjected to SDS PAGE followed by western blot with 15421-1-AP (ATP citrate lyase antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours.

The N-glycosylase activity releases damaged pyrimidines from double-stranded DNA, generating a basic (AP site). The AP-lyase activity of the enzyme cleaves 3´ to the AP site leaving a 5´ phosphate and a 3´ ring opened sugar. 1999-04-01 AP Lyase (n.) 1. ( MeSH ) A DNA repair enzyme that catalyses the excision of ribose residues at apurinic and apyrimidinic DNA sites that can result from the action of DNA GLYCOSYLASES.

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 ). Apurinic/apyrimidinic (AP) site recognition by the 5'-dRP/AP lyase in poly(ADP-ribose) polymerase-1 (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. In cell extracts, sodium borohydride reduction of the PARP-1/AP site DNA complex resulted in (2008) AP lyase.

We previously demonstrated mammalian Ku has intrinsic 5' deoxyribosephosphate (5'dRP) and apurinic/apyrimidinic (AP) lyase activity, and showed this activity is important for excising abasic site damage from ends. Here we employ systematic mutagenesis to … Catalyzes the excision of an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine = 8-oxoG) from DNA (PubMed:10521423, PubMed:19446526).

a, b, Activity assays were performed in triplicate, stopped after 5, 10, 20, and 40 … Endonuclease III (Nth) protein from E. coli acts as both N-glycosylase and a AP-lyase. The N-glycosylase activity releases damaged pyrimidines from double-stranded DNA, generating a basic (AP site).

Endonuclease with N-glycosylase activity, releasing damaged pyrimidines to form AP sites, and AP-lyase activity which cleaves 3' to the AP site.

During AP site cleavage by the AP lyase activity of DNA glycosylases, an aldimine intermediate between the C1′ atom of deoxyribose and a primary amine group in the protein is formed (3, 13, 14). This intermediate, termed the Schiff base, can be reduced in vitro by sodium borohydride (NaBH 4 ) treatment, forming an irreversible covalent complex between the enzyme and DNA ( 3 , 13 , 14 ). Apurinic/apyrimidinic (AP) site recognition by the 5'-dRP/AP lyase in poly(ADP-ribose) polymerase-1 (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.

2013-06-01 · ALKBH1’s AP lyase activity does not require Fe 2+ or 2-oxoglutarate and is unaffected by mutation of the putative metal-binding residues . Of use for a facile assay, ALKBH1 can introduce DSBs into oligonucleotides containing AP sites in close proximity on opposing strands .

Also cleaves the DNA backbone at apurinic/apyrimidinic sites (AP sites) (PubMed:10521423, PubMed:19446526). Has little specificity for the base opposite oxoG (PubMed:10521423). Monofunctional vs. bifunctional glycosylases.
