What is it about?
Water around the protein and the water we drink are very different. Ever wonder how this '21th amino acid', the bound water control protein stability? The hunch is that more restricted the water dynamics is, more stable is the protein. It's not like that. Taking crowded environment, we showed that the stability of protein and water could only be understood in terms of individual entropy and enthaly of stability rather than overall stability and it's more complex than we thought.

Why is it important?
Protein stability is one of the oldest and debated topic of fundamental bioscience. Here, we give a new outlook to understand it. Proteins are evolved to behave in crowded milieu, and there are many findings of protein stability on crowded milieu (like negative entropy effect and entropy enthalpy compensation) that so far could not be explained. This story explains most of these.
