Molecular recognition

Crystal structure of a short peptide L-Lys-D-Ala-D-Ala (bacterial cell wall precursor) bound to the antibiotic vancomycin through hydrogen bonds[1]
Crystal structure of two isophthalic acids bound to a host molecule through hydrogen bonds[2]
Static recognition between a single guest and a single host binding site. In dynamic recognition binding the first guest at the first binding site induces a conformation change that affects the association constant of the second guest at the second binding site. In this case it is positive allosteric system.

The term molecular recognition refers to the specific interaction between two or more molecules through noncovalent bonding such as hydrogen bonding, metal coordination, hydrophobic forces,[3][4] van der Waals forces, π-π interactions, halogen bonding, or resonant interaction[5] effects. In addition to these direct interactions, solvents can play a dominant indirect role in driving molecular recognition in solution.[6][7] The host and guest involved in molecular recognition exhibit molecular complementarity. Exceptions are molecular containers,[8][9] including, e.g., nanotubes, in which portals essentially control selectivity.[10][11][12][13] Selective partioning of molecules between two or more phases can also result in molecular recognition.[14] In partitioning-based molecular recognition the kinetics and equilibrium conditions are governed by the presence of solutes in the two phases.[15]
