L asparaginase a review

Present review provides thorough information on microbial l asparaginase bioprocess optimization including submerged fermentation and solidstate fermentation for l asparaginase production downstream purification its characterization and issues related to the clinical application. L-asparaginase also known as aminohydrolase pertains to the amidase group of enzymes and can break down amino acid L-asparagine into aspartate and ammonia 3 Fig.

The purpose of this systematic review was to identify the available literature of the l -asparaginase producing fungi.

L asparaginase a review. Alves Screening and optimizing fermentation production of lasparaginase by Aspergillus terreus strain S18 isolated from the Brazilian Caatinga Biome Journal of Applied Microbiology 126 5 1426-1437 2019. Pieces of information about the three-dimensional structure of L-asparaginase from Escherichia coli and Erwinia sp. Have identified residues that are essential for catalytic activity.

This review catalogues the major sources of L-asparaginase the methods of its production through the solid state SSF and submerged SmF fermentation purification and characterization as well as its biological roles. Occurrence of l-asparaginases in fungi yeasts bacteria and animal cells and their antitumour effects were reviewed in many articles 84 85 but the majority of l-asparaginases cannot be. A remarkable achievement in the field of medicine was the development of the L-Asparaginase enzyme as an effective antitumor agent.

L-Asparaginase ASNase inhibits protein synthesis in T-cells by catalyzing the conversion of L-asparagine to L-aspartate and ammonia and this catalytic reaction is essentially irreversible under physiological conditions. The enzyme L-Asparaginase has. 3511 also known as L-asparagine amidohydrolase is the enzyme with anti-tumor activity and is well accepted as a chemotherapeutic agent against the acute lymphoblastic leukemia and lymphosarcoma.

L-asparaginase is a critical part of the treatment of acute lymphoblastic leukaemia in children and adolescents and has contributed to the improvement in patient outcomes over the last 40 years. The main products used in clinical treatment are L-asparaginase enzymes derived from Escherichia coli and Erwinia chrysanthemi. Serum level of asparaginase 100 IUL corresponds to depletion of asparagine ie below the level of quantifica-tion27 and therefore is often considered the target trough asparaginase level.

Complete asparagine depletion is observed less frequently with enzyme concentrations below this level4344 However there is some evidence to suggest that trough asparaginase levels of below 50 IUL. A high rate of hypersensitivity and adverse reactions limits the longterm clinical use of l asparaginase. Present review provides thorough information on microbial l asparaginase bioprocess optimization including submerged fermentation and solidstate fermentation for l asparaginase production downstream purification its characterization and issues related to the clinical application.

Also this review lists the sources of L-asparaginase and L-glutaminase production optimization of enzymes and uses of the two enzymes in cancer therapy and other industrial purposes. L-asparaginase causes certain side effects and despite its potential antileukemic activity utilization of l-asparaginase by leukemic patients causes lethality to normal cells. L -asparaginase produces a broad range of symptoms such as edema skin rashes fever hepatic dysfunction diabetes leucopenia pancreatitis neurological seizures and hemorrhage 35 36.

Graphical summary of l asparaginase. The purpose of this systematic review was to identify the available literature of the l -asparaginase producing fungi. This study followed the Preferred Reporting Items for Systematic Reviews.

L-asparaginase also known as aminohydrolase pertains to the amidase group of enzymes and can break down amino acid L-asparagine into aspartate and ammonia 3 Fig. L-asparaginase is the first therapeutic enzyme with antineoplastic properties that has been studied broadly by researchers and scientists far and wide. This review hence mainly focuses on the biochemical aspects of L-asparaginase production aiming to comprehend the physiochemical characteristics application and assay methods of L-asparaginase enzyme properties and kinetics of recombinant enzyme production by fermentation.
