antipersonnel 5. Associated Press 6. author's proof American Heritage® Dictionary of the The purification and characterization of a pyrimidine dimer-specific glycosylase/AP lyase from Bacillus sphaericus (Bsp-pdg) are reported. Bsp-pdg is highly specific for DNA containing the cis-syn cyclobutane pyrimidine dimer, displaying no detectable activity on oligonucleotides with trans-syn I, trans-syn II, (6-4), or Dewar photoproducts. 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of each family, the enzymes Nfo and fpg, respectively, cleave nucleic acid backbones at positions in which a base has been replaced by a linker to which a variety of label moieties may be attached. ATP citrate lyase (ACLY) Probes with a p < 0.05 and a >2‐fold change relative to the control siRNA were considered significant.

We used mouse dermal fibroblasts 13 deficient in Ku70 and p53, either complemented by 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. 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).

The AP lyase experiments with different Topo-V fragments suggested that the lyase active site is located between residues 556 and 599.

In Arabidopsis, AtOGG1 is a DNA glycosylase/apurinic/apyrimidinic (AP) lyase that is involved in base excision repair for eliminating 8-oxo-G from DNA. In this study, the functions of AtOGG1 were elaborated. 8-oxo-dG glycosylase/AP lyase activity in crude mitochondrial extracts was measured by an oligonucleotide incision assay, as previously described . Briefly, RHM or RLM were resuspended in a buffer containing 20 mM HEPES-KOH (pH 7.6), 1 mM EDTA, 2 mM DTT, 300 mM KCl, 5% glycerol and 0.05% Triton X-100. The AP-lyase activity cleaves both 3´ and 5´ to the AP site thereby removing the AP site and leaving a 1 base gap.

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 . AP lyase activity also was seen in Alkbh1 of Saccharomyces pombe .

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.

Associated Press 6. author's proof American Heritage® Dictionary of the 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.
