Webb17 mars 2006 · In contrast to the lock and key recognition of loop E, recognition of loop A by finger 6 follows a mutually synergistic induced-fit model, as has been observed in many other RNA–protein interactions. 23 The highly conserved CAUA motif of loop A, at the junction between the three helical stems, is conformationally disordered in the free RNA … Webb8 juli 2024 · 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.

Webb26 sep. 2024 · Enzymes are highly specific protein molecules that increase the rate of reaction whilst not being changed by the reaction and in some cases require cofactors. The active site of an enzyme is the site where the substrate binds and where the reaction takes place. There are two hypotheses as to how the enzymes fit their specific substrates: …
