== Publication Abstract from PubMed ==
 +
Split inteins are expressed as two separated subunits (N-intein and C-intein) fused to the corresponding exteins. The specific association of both intein subunits precedes protein splicing, which results in excision of the intein subunits and in ligation, by a peptide bond, of the concomitant exteins. Catalytically active intein precursors are typically too reactive for crystallization or even isolation. Neq pol is the trans-intein of the B-type DNA polymerase I split gene from hyperthermophile Nanoarchaeum equitans. We have determined the crystal structures of both the isolated NeqN and the complex of NeqN and NeqC subunits carrying the wild-type sequences, including the essential catalytic residues Ser1 and Thr+1, in addition to seven and three residues of the N- and C-exteins, respectively. These structures provide detailed information on the unique oxyester chemistry of the splicing mechanism of Neq pol and of the extensive rearrangements that occur in NeqN during the association step.
