1LWS, 1LWT - PubMed Abstract: 
The first X-ray structures of an intein-DNA complex, that of the two-domain homing endonuclease PI-SceI bound to its 36-base pair DNA substrate, have been determined in the presence and absence of Ca(2+). The DNA shows an asymmetric bending pattern, with a major 50 degree bend in the endonuclease domain and a minor 22 degree bend in the splicing domain region ...
