HHsearch alignment for GI: 254780636 and conserved domain: cd06126

>cd06126 DEDDy DEDDy exonucleases, part of the DnaQ-like (or DEDD) exonuclease superfamily, catalyze the excision of nucleoside monophosphates at the DNA or RNA termini in the 3'-5' direction. They contain four invariant acidic residues in three conserved sequence motifs termed ExoI, ExoII and ExoIII. DEDDy exonucleases are classified as such because of the presence of a specific YX(3)D pattern at ExoIII. The four conserved acidic residues serve as ligands for the two metal ions required for catalysis. DEDDy exonucleases include the proofreading domains of DNA polymerases (families A and B), as well as RNases such as RNase D and Rrp6p. The Egalitarian (Egl) and Bacillus-like DNA Polymerase I subfamilies do not possess a completely conserved YX(3)D pattern at the ExoIII motif. In addition, Bacillus-like DNA polymerases contain inactive 3'-5' exonuclease domains which do not possess the metal-binding residues necessary for activity.
