The Active Groups present in the cavities present surface of enzyme is/are
Answers
Ans :-) The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
The active site consists of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyse a reaction of that substrate (catalytic site).
Although the active site occupies only ~10–20% of the volume of an enzyme,[1]:19 it is the most important part as it directly catalyzes the chemical reaction.
It usually consists of three to four amino acids, while other amino acids within the protein are required to maintain the tertiary structure of the enzyme.
The Active Groups present in the cavities of various enzymes are as follows:
- Sulphate :
- Phosphate :
- Serine
- Histidine
- Tyrosine
- Arginine
- Cysteine
Active sites are small pockets in the 3 - dimensionally packed enzyme molecule. It is essentially responsible for binding of the substrate and subsequent catalysis of the reaction to form products.
Active sites have 2 parts :
- Substrate Binding part : Attaches the substrate in a reversible manner via various non-covalent bonds.
- Catalytic part : Helps in the catalysis of the reaction to form products.
