Enzymes classification
Enzymes is protein,
Enzyme Increase the rate of reaction
Enzymes can be classified into six major classes based on the nature and type of reaction catalyzed as given.
- Oxidoreductase
- Transferase
- Hydrolase
- Layses
- Isomerase
- Liagases.
Oxidoreductase
enzyme catalysed oxidation or reduction by transfer of hydrogen or electron examples Succinic dehydrogenase.
Transferases.
Enzyme are involved in transfer of functional group with donor and acceptor.
Example are glutamic pyruvic transminase.
Hydrolases
Enzymes can be transfer of water group.
Reaction involved hydrolytic cleavage of c-o, c- n ,o- p , and c-s bonds.
Example peptidases.
Proteolytic enzymes are special class of hydrolases.
Layses
These enzymes remove the group of water ammonia or carbon dioxide from this substrate to cleave double bond.
Example furmarase.
Isomerases
these are a very heterogeneous group of enzymes that catalyze isomerasation.
These include cis-trans ,keto-enol and adose-ketose interconversion.
Isomerases that catalyse inversion at asymmetric carbon are either epimerase or racemase.
Example Mutases
Liagases (synthetases)
These enzymes are joined together also involved in synthetic reaction.
Example pyruvic carboxylase.
