| + | [https://www.uniprot.org/uniprot/DPOL_THEKO DPOL_THEKO] Intein encoded endonucleases are thought to mediate intein mobility by site-specific recombination initiated by endonuclease cleavage at the "homing site" in gene that lack the intein. PI-PkoI recognizes 5'-GATTTAGATCCCTGTACC-3' and PI-PkoII recognizes 5'-CAGCTACTACGGTTAC-3'. | ||

| + | Archaeal B-family polymerases drive biotechnology by accepting a wide substrate range of chemically modified nucleotides. By now no structural data for archaeal B-family DNA polymerases in a closed, ternary complex are available, which would be the basis for developing next generation nucleotides. We present the ternary crystal structures of KOD and 9 degrees N DNA polymerases complexed with DNA and the incoming dATP. The structures reveal a third metal ion in the active site, which was so far only observed for the eukaryotic B-family DNA polymerase delta and no other B-family DNA polymerase. The structures reveal a wide inner channel and numerous interactions with the template strand that provide space for modifications within the enzyme and may account for the high processivity, respectively. The crystal structures provide insights into the superiority over other DNA polymerases concerning the acceptance of modified nucleotides. | ||
