Lock and Key Model - Medical Dictionary

WebThe textbook lock-and-key model for enzyme catalysis was first introduced by the Nobel laureate organic chemist Emil Fischer in 1894 (Fischer, 1894).The induced-fit and the … WebA Lock and Key analogy may be used to describe the fundamental action of a single substrate enzyme. In this case, the enzyme is the lock, and the substrate is the key. Only the correct size key, which is the substrate, enters the keyhole, which is the active site of the lock, which is the enzyme. Other keys that are too tiny, too big, or have ...
