Hesham Saeed, Hadeer Ali, Hadeer Soudan, Amira Embaby, Amany El-Sharkawy, Aida Farag, Ahmed Hussein, Farid S. Ataya. Molecular cloning, structural modeling and production of recombinant Aspergillus terreus L. asparaginase in Escherichia coli. Internat

l-Asparaginase (EC 3.5.1.1) is an important medical enzyme that catalysis the hydrolysis of l-asparagine to aspartic acid and ammonium. For over four decades l. asparaginase utic agent for the treatment of a variety of lymphoproliferative disorders and lymphoma such as acute lymphoblastic leukemia. In the present study A. terreus full length l. asparaginase gene, 1179bp was optimized for expression in Escherichia coli BL21 (DE3) pLysS. The full length A. terreusl. asparaginase gene encoding a protein of 376 amino acids with estimated molecular weight of 42.0kDa and a theoretical isoelectric point (pI) of 5.0. BLAST and phylogeny analysis revealed that the A. terreusl. asparaginase shared high similarity with other known fungal l. asparaginase (75% homology with A. nomius and 71% with A. nidulans). The recombinant protein was overexpressed in the form of amorphous submicron proteinaceous inclusion bodies upon induction with 1mM IPTG at 37°C for 18h.
