Asparagine (Asn or N) ((2S )-2-amino-3-carbamoyl-propanoic acid) is a polar, uncharged amino acid with the formula HOOCCH(NH2)CH2CONH2. It has a carboxamide as the side chain s functional group. Asx or B represent either Asn or Asp. Asn are often found near the beginning and end of alpha-helices, and in turn motifs in beta sheets. ...

Attempts to use other features to classify the interfaces, such as the types of structural motifs of the protein (helix, beta, helix-turn-helix) or of the DNA (minor or major groove) involved in binding, have not yielded clear patterns thus far. More data on the structures of protein-DNA complexes are clearly needed in order to provide a better basis for performing classifications of the different types of protein-DNA complexes.
