Classes of Enzymes
Main classes of enzymes
Question | Answer |
---|---|
1. Oxidoreducterase | catalyzes redox reactions Subclasses: Oxidases, Reductases, Dehydrogenases |
2. Transferases | Catalyze the transfer of functional groups between 2 substrates Subclasses: transaminases, kinases |
3. Hydrolases | catalyze hydrolysis reactions - the addition of a water molecule causes the bond to break Subclasses: Lipases, proteases, nucleases, carbohydrases, phosphatases |
4. Lyases | Catalyze the addition of a group to a double bond or the removal of a group to create a double bond without involving hydrolysis Subclasses: dehydrases, decarboxylases, deaminases |
5. Isomerases | Catalyze the conversion of a substrate into another compound that is isomeric with it. Converts D isomer to L isomer or L isomer to D isomer Subclasses: racemases, mutases |
6. Ligases | Catalyze the bonding of 2 substrate molecules, with participation of ATP Subclasses: synthases, carboxylases |
