Location Within Cell
Enzyme Substrate Complex
Tempreture Sensitivity
Reversibility of reaction
Unchanged form
High Efficiancy
Protien Nature
PH Sensitivity
CLASSIFICATION OF ENZYMES
ON THE BASIS OF TYPE OF REACTION
4}}
Lysases
Catatyzes the cleavage of C-C, C-O, C-N bonds by other means than by hydrolysis or oxidation..Catalyze a group elimination in order to form double bonds (or a ring structure).
5}}
Isomerases
3}}
Hydrolases
Catalysts that use water to cleave chemical bonds, usually dividing a large molecule into two smaller molecules.
6}}
Ligases
2}}
Transferases
Transfer of specific functional groups
Catalyze hydrolysis reactions
1}}
Oxidoreductases
transfer of electrons
from
Reductants (electron donors) to oxidants (electron acceptors)
ON THE BASIS OF SITE OF ACTION
Inracellular
Extracellular
ON THE BASIS OF COMPOSITION
CONJUGATE ENZYMES
Cofactor
May be
Inorganic
Metal Activators
Metal Activated Enzymes
Metalloenzymes
Organic
Prosthetic group
Coenzyme
Not too specific
Heat Stable
small in size
non protein part
Apoenzyme
#
specific for an enzyme
i large in size
protein part of the holoenzyme
Takes part only in catalytic activity
SIMPLE ENZYMES
Composed of only Protien
Eg:- trypsin,pepsin,etc.
