Stability of "salt bridges" in membrane proteins.
We estimate the free energies of transfer of ionized amino acid side chains in water to both their ion-paired and neutral hydrogen-bonded states in low-dielectric media. The difference between the two free energies corresponds to the proton transfer free energy in a "salt bridge" formed between acidic and basic groups (i.e., lysine and glutamic acid residues). Our approach is to use gas phase p...

absorbed in the atmosphere, the NIR water vapor bands. Thus, we see no way of defending Stephen's statement that conclusions based on broad-band measurements (1) are inconsistent with other existing data sets where discrepancies were found to occur between measurements in spectral bands and theory. Instead, the broad-band solar absorption findings presented in our report (1) are entirely consis...
متن کاملDefining the role of salt bridges in protein stability.
Although the energetic balance of forces stabilizing proteins has been established qualitatively over the last decades, quantification of the energetic contribution of particular interactions still poses serious problems. The reasons are the strong cooperativity and the interdependence ofnoncovalent interactions. Salt bridges are a typical example. One expects that ionizable side chains frequen...
متن کاملESBRI: A web server for evaluating salt bridges in proteins
UNLABELLED Salt bridges can play important roles in protein structure and function and have stabilizing and destabilizing effects in protein folding. ESBRI is a software available as web tool which analyses the salt bridges in a protein structure, starting from the atomic coordinates. In the case of protein complexes, the salt bridges between protein chains can be evaluated, as well as those am...
