Salt Bridges

The association of two ionic groups of opposite charge is known as an ion pair or salt bridge with a short r such as 4 A in equation 1. There are only a few salt bridges in proteins, with the exception of phosphoproteins and some glycoproteins. These salt bridges amount to about 10-20 kcal/mol for adjacent carboxylate and ammonium groups. This value is higher than 3 kcal/mol of hydrogen bonds (35). Salt bridges are formed by about one-third of the charged residues; only 20% of these bridges are buried.
