Short summary
Many natural environments differ in their range of salt concentration (salinity). We developed a metric for the number of water molecules in formation reactions of different proteins and found that it decreases between freshwater and marine systems and also in laboratory experiments with increasing salinity. These results demonstrate a new type of link between geochemical conditions and the chemical composition of microbial communities that can be useful for models of microbial adaptation.
