Active Sites:
- Enzymes bind the specific substrates on regions called active sites to form enzyme-substrate complexes.
- By binding substrates, enzymes stabilize the energy of the transition state, which in turn stimulates the breakage of old bonds and formation of new bonds.
- At a constant concentration of enzyme, the enzyme activity will continue to rise up until a certain maximal value.
- This maximal value represents the condition in which all the active sites are filled with the appropriate substrate.
- The active site is a specific region on enzymes that binds to the substrate.
- The active site is a three-dimensional crack in the enzyme that contains the catalytic groups which catalyse the actual reaction.
- As enzymes are proteins, the active sites have a combination of unique amino acid residue.
- Each residue has a different property.
- These properties provide specific environment suited to bind to a very specific chemical substrate.
- Active sites stabilize the transition state.
- Active sites make up only a small component of the overall enzyme. The remaining portion of the enzymes acts to create and support the active site by bringing residues together.
-
A particular enzyme can catalyse only a particular type of reaction.
