One can think of molecular docking as a problem of “lock-and-key”, in which one wants to find the correct relative orientation of the “key” which will open up the “lock” (where on the surface of the lock is the key hole, which direction to turn the key after it is inserted, etc.). Here, the protein can be thought of as the “lock ...
Molecular imprinting is a technique to create template-shaped cavities in polymer matrices with predetermined selectivity and high affinity. [1] This technique is based on the system used by enzymes for substrate recognition, which is called the "lock and key" model.
Antigen and antibody interact through a high affinity binding much like lock and key. [10] A dynamic equilibrium exists for the binding. For example, the reaction is a reversible one, and can be expressed as: [11] [] + [] []
Macromolecular docking is the computational modelling of the quaternary structure of complexes formed by two or more interacting biological macromolecules. Protein–protein complexes are the most commonly attempted targets of such modelling, followed by protein–nucleic acid complexes.
The induced fit model is a development of the lock-and-key model and assumes that an active site is flexible and changes shape until the substrate is completely bound. This model is similar to a person wearing a glove: the glove changes shape to fit the hand. The enzyme initially has a conformation that attracts its substrate.
In molecular biology, complementarity describes a relationship between two structures each following the lock-and-key principle. ... For example, hypoxia-induced ...

By understanding the method in which substances move along neurons or microtubules it is possible to target specific pathways for disease. Currently, many drug companies are aiming to utilize the trajectory of intracellular transport mechanisms to deliver drugs to localized regions and target cells without harming healthy neighboring cells.
