Endo and exonuclease
WebJun 20, 2016 · Artemis is a vertebrate nuclease with both endo- and exonuclease activities that acts on a wide range of nucleic acid substrates. It is the main nuclease in the non-homologous DNA end-joining pathway (NHEJ). Not only is Artemis important for the repair of DNA double-strand breaks (DSBs) in NHEJ, it … WebNov 11, 2015 · The endo- and exonculease activities have distinct requirements: whereas the exonuclease activity on linear DNA fragments is stimulated by HerA and depends on the catalytic D58 residue, the endonuclease activity on circular double-stranded DNA is HerA-independent and is not affected by the D58A mutation. On the basis of our results …

We crystallized and solved informative Mre11 structures with PFM01, PFM03 (endo inhibitors), and PFM39 (exo inhibitor) to 2.3, 2.4, and 2.3 Å, respectively. The Mre11 microbial avatar pinpointed two specific sites where small molecules can bind and modulate nuclease activity.
WebEndo-exonucleases from E. coli to man, although very different proteins, are multifunctional enzymes with similar enzymatic activities. They probably have two common but opposing biological roles.
