Isolation of L-Asparaginase Enzyme from Microbes

Abstract: L-Asparaginase (EC 3.5.1.1) is a crucial enzyme with significant therapeutic applications, especially in the treatment of acute lymphoblastic leukemia (ALL). It catalyzes the hydrolysis of L-asparagine into L-aspartate and ammonia, thus depleting the supply of asparagine, which is essential for the survival of certain tumor cells. L-Asparaginase is produced by various microorganisms, including bacteria, fungi, and actinomycetes. The microbial production of this enzyme has drawn attention due to its cost-effectiveness, ease of fermentation, and ability to produce high yields. This review article focuses on the microbial sources of L-Asparaginase, methods of isolation and purification, and the importance of optimizing the production conditions for industrial and therapeutic applications.
