20.109(S17):Identify chemical structures common among FKBP12 binders
Contents
Introduction
Proteins and small molecules interact in a process referred to as molecular recognition. In molecular recognition, the non-covalent complexes that form are defined by two characteristics: specificity and affinity.
- Specificity distinguishes a specific binding partner from the milieu of potential binding partners in complex environments.
- Affinity dictates the likelihood of binding based on the concentration of a specific binding partner in a milieu of potential binding partners such that high affinity partners at low concentrations are not outcompeted by low affinity partners and high concentrations.
In cells, proteins are critical macromolecules that perform numerous roles related to structure, mechanics, metabolism, and signaling. In these roles, proteins do not work in a vacuum; rather the biological roles of proteins are dependent on direct physical interactions with other molecules. Though our focus in on small molecule binders, proteins also interact with other proteins, nucleic acids, oxygen, and metals. In all cases, the interactions are characterized by protein-ligand-solvent binding kinetics.
