Abstract

We report the first example of chemical cross-linking of 5-formyl-2'-deoxyuridine containing Oligonucleotides with oligopeptides through a Schiff base formation. Twenty amino acid residue Peptides investigated here were derived from the DNA binding site of RecA protein. We have demonstrated that the lysine residue placed at the 6th or 8th position from the N-terminus of the peptide directly contacts with DNA.
