The “lock and key” model was first proposed in 1894. In this model, an enzyme’s active site is a specific shape, and only the substrate will fit into it, like a lock and key.

In anger, she questions what is wrong with her lock and key. Alfred, the science app, responds by explaining how enzymes work in relation to the ‘lock and key’ model.

Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates named DNA Vault. Read more.

There are two theories explaining the enzyme-substrate interaction. In the lock-and-key model, the active site of an enzyme is precisely shaped to hold specific substrates.

Enzymes are molecular machines that carry out the chemical reactions that sustain all life, an ability that has captured the attention of scientists like me.

But new work shows that shape complementarity — the construction of colloids using a lock-and-key recognition mechanism — offers a simple and effective alternative control mechanism.

Lock and key model Enzymes are folded into complex shapes that allow smaller molecules to fit into them. The place where these molecules fit is called the active site .

Madonna’s Daughter Lourdes Leon Breaks Into Music as Lolahol With Debut Single ‘Lock&Key’ Leon shared her debut single "Lock&Key" on Wednesday (Aug. 24) under the moniker Lolahol.

After saying that this was “certainly not off the table,” the company launched a new smart lock named “Level Lock+” that does work with Apple Home Key.

Yale today announced the launch of the Yale Assure Lock 2 Plus, its latest smart lock that has HomeKit integration and Apple Home Key support. With ...

Enzymes significantly speed up the chemical reactions that keep you alive. Researchers are using AI to create new ones to tackle modern challenges.
