3 - unsaturated aldehyde require additional processing by a phosphodiesterase. - "Characterizing Ku's Role as an AP lyase in Nonhomologous End Joining"

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. In: Encyclopedia of Genetics, Genomics, Proteomics and Informatics.

A. 1 nM radiolabeled AP substrate containing an abasic site was incubated at 37°C for 10 min with 2 nM Ku or the 2A/6A mutant Ku described in These differences in structure, yet similarity in function, led to the question of whether conserved structural motifs exist among glycosylases with AP lyase activity.In order to explore the idea that conserved structural motifs might exist within proteins that catalyze the initiation of repair at pyrimidine dimers, a collab-Ž . oration with New England Biolabs Beverly, MA was begun in which 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 … The Ku AP lyase activity is also strongly suppressed by as little as two paired bases 5′ of the abasic site.

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.

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). Also cleaves the DNA backbone at apurinic/apyrimidinic sites (AP sites) (PubMed:10521423, PubMed:19446526).
