Proteins are complex structures whose overall stability critically depends on a delicate balance of numerous interactions of similar strength, which are markedly influenced by their environment. Here, we present an analysis of the effect of pH on a protein structure in the crystalline state using RNase A as a model system. By altering only one physico-chemical parameter in a controlled manner, we are able to quantify the structural changes induced in the protein. Atomic resolution X-ray… CONTINUE READING
