Study Notes
Enzyme Classification and Functions
- Enzymes catalyzing oxidation-reduction reactions belong to the class of oxidoreductases.
- Enzymes that add oxygen to a substrate are also classified as oxidoreductases.
- Peroxidase and catalase enzymes are part of the oxidoreductase class, specifically involved in oxidation-reduction processes.
- Enzymes that remove hydrogen atoms from molecules are classified as dehydrogenases, a subgroup of oxidoreductases.
- Enzymes facilitating the transfer of electrons between molecules are categorized as oxidoreductases.
Classifications and Subgroups
- Enzymes are classified under six major classes based on their functional roles.
- Each class of enzymes has multiple subgroups, which categorize enzymes into more specific roles.
- The total number of enzyme subclasses across all six classes is over 100, indicating a wide range of functions.
Grouping Within Classes
- Enzymes within each class are grouped based on their specific catalytic roles and the nature of the chemical transformations they facilitate.
- The EC subclass responsible for transferring functional groups between molecules is transferases.
- Enzymes involved in the addition or removal of water molecules during reactions belong to the hydrolases or lyases, depending on the specific function.
- For catalyzing the breaking and forming of covalent bonds within a molecule, enzymes classified under ligases are most appropriate.
- Reactions involving stereochemical rearrangements are conducted by the isomerases subclass.
- Enzymes that transfer electrons between molecules are likely classified under the oxidoreductases EC subclass.
