Enzymes are classified according the reaction they catalyze. The six
classes are:
1 . Oxidoreductases
2.
Tranferases
3.
Hydrolases
4.
Lyases
5.
Isomerases
6.
Ligases
Examples
Examples
1.
Alcohol dehydrogenase: An
oxidoreductase converting alcohols
to
2.
aldehydes/ketones.
3.
Aminotransferases: Transferases catalyzing the amino acid
degradation
by removing amino groups.
3. Pyruvate decarbotylase: A lyase that removes €02
from pyruvate.by removing amino groups.
