“…If DNA and RNA double helices rather than individual nucleic acid bases are considered, the situation changes because several hydrogen-bonding recognition sites on the bases are now hidden by Watson-Crick-type base-pairing (Figure 18-3). Model building (1204,1205) and theoretical studies (1206) indicate that, as mentioned above, specific association between base-pairs embedded in double helices and amino acid side chains (or peptide groups) requires again the simultaneous formation of at least two hydrogen bonds. The minor (small) groove has the potential for distinguishing only between guanine and other bases (due to the unique guanine N2 amino group).…”

“…-Instrumental in the recognition of the guanine bases is an Arg residue on each arm, because of the well-documented possibilities of bidentate interactions occurring with 06 and N7 (16)(17)(18)(19)(20)(21). In the ~-sheet conformation, with Arg occurring as the first residue in the sequence, a L configuration of theCa carbon is necessary to orient the side chain towards the major groove whilst avoiding steric clashes.…”

“…a) The recourse to Arg rather than Lys or Orn as a cationic residue, on account of the well-documented capacity of this base to recognize guanine bases in the major groove (16)(17)(18)(19)(20)(21); energy balances including desolvation at the site of interaction resulted in a more favorable binding energetics for arginine rather than lysine binding to guanine (21).…”

“…Selectivity can only be possible if the electrostatic forces can cooperate with additional forces, which are governed by the 'conformation fit mechanism', existing only in the case of oligomers. Interactions governed by conformation have also been postulated by other authors as essential elements of the protein-DNA interaction [23,24]. In this paper the existence of such intcractions is proved experimentally and measured for the first time.…”
