“Over The HILL“
Classification of enzymes:
1).Oxidoreductases: catalyzes the transfer of hydrogen or oxygen atom or electrons from one substrate to the other. (Redox reactions).
E.g., Oxidases, Dehydrogenases, Oxygenases, Peroxidases, Catalases.
2).Transferases: catalyzes the transfer of a functional group from one substrate to the other.
E.g., Kinases, Transaminase.
3).Hydrolases: catalyzes hydrolysis or breakdown of the substrate.
E.g., Esterase, digestive enzymes, lysozyme, acid phosphatase.
4).Isomerases: catalyzes intramolecular changes in the substrate.
E.g., Isomerase, Fumarase.
5).Lyases: catalyzes the non-hydrolytic removal of a group or addition of a group to a substrate.
E.g., Decarboxylases, Aldolases.
6).Ligases (Synthetases): catalyzes joining of two molecules by forming new bonds.
E.g., Citric acid synthetase.
