Question

Enzyme asparaginse is obtained from:

• A. Clostridium histolyticum
• B. Bacillus subrills
• C. Erwinia caratovora
• D. Khuyveromycas lactis

Answer 1

The Correct Option is C

The enzyme asparaginase is primarily used in the treatment of various types of leukemia due to its ability to hydrolyze the amino acid asparagine into aspartic acid, thus depriving cancer cells of asparagine, which they need to grow. The production of asparaginase from different microbial sources is an important area of study in the field of biochemistry and biotechnology.

Let's analyze the options given:

1. Clostridium histolyticum: This bacterium is known for producing collagenase, which is an enzyme that breaks down collagen. It is not recognized for producing asparaginase.
2. Bacillus subrills: It seems there is a typographical error here. If it refers to Bacillus subtilis, this bacterium is known for producing a variety of enzymes but not specifically asparaginase.
3. Erwinia caratovora: This is the correct answer. Erwinia carotovora (also spelled Erwinia caratovora) is known to produce L-asparaginase, making it a source of this enzyme for medical applications.
4. Khuyveromycas lactis: Correctly spelled as Kluyveromyces lactis, this is a yeast used in the dairy industry for the production of lactose-free products; it is not related to asparaginase production.

Therefore, the correct option is Erwinia caratovora, as it is a known producer of asparaginase used in therapeutic applications to treat leukemia patients by depriving cancer cells of asparagine.
