Water binding

Water binding describes the phenomenon where water molecules interact with biological macromolecules—such as proteins and nucleic acids—through hydrogen bonding and other non-covalent interactions. These bound waters can play critical roles in stabilizing three-dimensional structures of proteins and nucleic acids, mediating enzymatic reactions (e.g., acting as proton donors/acceptors), facilitating molecular recognition events (such as transcription factor-DNA interactions), influencing folding dynamics, and modulating thermodynamic properties at biomolecular interfaces[1][3][4]. However, water binding itself does not refer to any specific gene product or druggable entity; rather it is an essential physicochemical property observed across many biological systems[1][3]. As such, it should not be considered a canonical therapeutic target but rather an important aspect of biophysical chemistry underlying many cellular functions.

Not applicable. Drugs do not act by targeting "water binding" per se.
