Types of Enzymes
As we all know that the enzymes are the made up of proteins and
Phospholipids, but generally enzymes are proteinaceous in nature. Simply we
can say that the enzymes are entirely consists of proteins.
Enzymes can be divided into two types on following bases:
Enzymes which are made up of only proteins. It is also known as simple
2. Conjugated Enzyme:
Enzymes which contains protein as a major part and also other substances
are attached to it, also know as Holoerzyme and this was proposed by Euler
The Conjugated Enzyme can be divided into types:
It is known as the part of holoenzyme which is made up of proteins only.
2. Prothestic Group:
The remaining part of Holoenzyme or the part of Holoerzyme other that
proteinases part is known as Prothestic Group.
The Prothestic Group is further divided into two types:
Co-factor is said when the prothestic group is an in-organic ions. For
example: mg, Ca, Mn, K on enzymes as phosphatases, phosphorylase, amidase,
peptidase, carboxylase is known respectively.
Co-enzyme is said, when the group is consists of organic molecules although
some inorganic ions may be present there. Co-enzyme is about 1% of enzyme.
It is that heat resistant so can be removed easily. For Example: NAD, NADP,
FMN, ATP etc.
