Research ArticleOpen accessEvery word in the titleIntracellular L-Asparaginase from Bacillus sp. PG02: Purification, Biochemical Characterization and Evaluation of Optimum pH and TemperatureFatemeh Izadpanah Qeshmi, Mahsa Rahimzadeh, Sedigheh Javadpour, Manijeh PoodatBacterial L-asparaginases are amidohydrolases that act on L-asparagine and produce L-aspartate and ammonia. These enzymes have been used in treatment of lymphoblastic leukemia. In the present study, a novel strain, Bacillus sp. PG02 was explored for the production of intra-cellular L-asparaginase enzyme. The nitrogen source for L-asparaginase production was L-asparagine. New intracellular L-asparaginase was purified using ion exchange chromatography and … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Nov 2015 · 7,480 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAn Optimized Medium for Screening of L-Asparaginase production by Escherichia coliYounes Ghasemi, Alireza Ebrahiminezhad, Sara Rasoul-Amini et al.Purified L-asparaginase II from Escherichia coli has been supplied and employed in the acute leukemia and other malignant neoplasms chemotherapy. L-asparaginase II gene (ansB) in E. coli is under regulation and certain conditions is needed for expression of this gene. In this investigation ,the various concentrations of modified M9 medium ingredients and various carbon source were tested to optimize the … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 9,698 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,081 accessesView PDF Cite
