The structure of I … Webgroup I intron was reported to be essential for DNA endonuclease activity of these proteins. In other proteins, the EXlHH-HX3H domain is hypothesized to possess DNase activity as well. Pre- sumably, this activity promotes movement (rearrangement) of group I and group I1 introns encoding the EX,HH-HX3H do- main and other gene targets.
