The basics of enzymes

Enzymes lower the activation energy of a reaction, thus accelerating the reaction rate of the conversion of substrate to product. The increased rate can be by a factor of several million and without this increased reaction rate, life would not be able to be sustained here on Earth.
Most enzymes are proteins, but there are a few exceptions where RNA molecules can act as catalysts for reactions.
Since the enzyme is a catalyst, it is not consumed during the reaction. Thus, decreased reaction rates observed over time is not due to the enzyme concentration decreasing, but a combination of reduced availability of substrates and an accumulation of product.
Enzymes often work within very narrow pH and temperature ranges. Hence, it is essential that you use the correct buffers and optimal temperature ranges given in the protocol that is supplied with the enzyme.
Enzymes can lower the activation energy (ΔG‡, Gibbs free energy) of a reaction in several ways.

  • Stabilization of the transition state

  • Providing alternative pathways

  • Destabilization of the substrate ground state

The nomenclature of enzymes is determined by the substrate that is used in the reaction and with the addition of the suffix -ase. One example of this would be the alcohol-metabolizing enzyme alcohol dehydrogenase.
Generally, enzymes are divided into the following groups:

Oxidoreductases: catalyze oxidation/reduction reactions

Ligases: can join molecules with covalent bonds

Transferases: can transfer functional groups, such as polymerases

Isomerases: can catalyze isomerization changes

Hydrolases: catalyze the hydrolysis of various bonds, including restriction enzymes

Lyases: cleave various bonds (not hydrolysis and oxidation)

Isozymes is the name given to enzymes that are different, but are catalyzing the same chemical reaction.

Our Restriction Enzyme Troubleshoot is useful for solving any potential problems.

Compare Enzymes

With our compare function, you can avoid all the time and energy wasted sifting through multiple web pages from different suppliers. At ZAGENO you can clearly see kits side-by-side, with the relevant attributes for each kit neatly in line for easy selection of the best product for you.

The ZAGENO comparison does not highlight one kit to be better than the other, as the kit of choice may vary between researchers - depending on each individual's preferred attributes. The best kit is the one that meets your needs - ZAGENO allows you to make an informed decision with minimum effort.
