| - | The role of surface salt bridges in protein stabilization has been a source of controversy. Here we present the NMR structure of a hyperthermophilic rubredoxin variant (PFRD-XC4) and the thermodynamic analysis of two surface salt bridges by double mutant cycles. This analysis shows that the surface side chain to side chain salt bridge between Lys 6 and Glu 49 does not stabilize PFRD-XC4. The main chain to side chain salt bridge between the N-terminus and Glu 14 was, however, found to stabilize PFRD-XC4 by 1. 5 kcal mol(-)(1). The entropic cost of making a surface salt bridge involving the protein's backbone is reduced, since the backbone has already been immobilized upon protein folding. | ||
