Model studies of interactions between nucleic acids and proteins: hydrogen bonding of amides with nucleic acid bases.
The formation of hydrogen bonded complexes between nucleic acid bases and acetamide has been studied by nuclear magnetic resonance in CDC13 at different temperatures. Pairs of hydrogen bonds are formed when acetamide binds to nucleic acid bases. Thermodynamic parameters have been computed and compared to those obtained for the association of carboxylic acids with nucleic acid bases. The role of hydrogen bonded complexes in the association of proteins with nucleic acids is discussed.
