Describe nomenclature of enzymes.
The enzymes are divided into 6 classes on the basis of the reaction they catalyse. Each subclass is futher divided into 4-13 classes.
The six classes of enezymes are -:
i. Oxidoreductases/dehydrogeneases : These are enzymes which catalyse oxidoredcuction reactions.
ii. Transferases: Enzymes catalysing transfer of group between a pair of substrates.
iii. Hydrolases Enzymes catalysing hydrolysis reactions.
iv. Lyases - Enzymes that catalyse removal of groups from substrates by methods other than hydrolysis, leaving double bonds.
v. Isomerases - Enzymes which carry out interconversion reactions.
vi. Ligases : Enzymes catalysing the linking of two compounds.
