(d) Asparaginase
Asparaginase is a purified enzyme commonly used in the pharmaceutical industry, particularly in the treatment of certain types of cancer, such as leukemia and lymphomas. It works by depleting the amino acid asparagine, which is essential for the growth of cancer cells.
While the other enzymes listed, such as Subtilisin, Novozym-435, and Bromelain, have industrial applications, Asparaginase is the one most directly associated with the pharmaceutical industry.
