Question

The following enzyme belongs to the Acyl-transferase group is

• A. Hydrolase
• B. Oxidase
• C. Transglutaminase
• D. Reductase

Hint:

Transglutaminase is often called "nature's glue." In surimi gelation, it catalyzes the formation of strong covalent bonds between myosin heavy chains, enhancing the elastic properties of fish paste.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Enzymes are classified into six major groups based on the type of chemical reactions they catalyze.
Transferases catalyze the transfer of a functional group from one molecule to another.

Step 2: Detailed Explanation:
Transglutaminase (TGase, EC 2.3.2.13) belongs to the transferase class, specifically acyltransferases.
It catalyzes the transfer of an acyl group (the \(\gamma\)-carboxamide group of a glutamine residue) to an amine acceptor (such as the \(\varepsilon\)-amino group of a lysine residue), forming covalent intra- and inter-molecular isopeptide bonds.
In fish processing, this enzyme is widely used to cross-link proteins in surimi to improve gel strength and texture.
- Hydrolases, oxidases, and reductases belong to separate EC classes.

Step 3: Final Answer:
The enzyme belonging to the acyltransferase group is Transglutaminase, corresponding to option (C).
