摘要
l -天冬酰胺酶似乎是非常有效的,特别是对儿童新诊断急性淋巴细胞白血病。延长l -天冬酰胺酶强化治疗可显著改善预后。目前,l -天冬酰胺酶是世界上用于治疗儿童急性淋巴细胞白血病的重要药物。它的潜力现在已经得到了充分的证实,因为它在大多数患有这种疾病的患者中显著地诱导了缓解。该疗法为现代肿瘤学带来了重大突破,随着其新功能的开发,预计l -天冬酰胺酶在未来几年将有很大的需求。为了保持这种特殊酶在癌症治疗中的潜力,目前的工作计划通过传统和基因工程技术来优化l -天冬酰胺酶的生产。选择胡萝卜乳杆菌进行本研究是基于其治疗癌症的潜力,以及与大肠杆菌来源的酶相比,其谷氨酰胺酶活性较低。从昌迪加尔的MTCC采购微生物培养物,用平板法筛选l -天冬酰胺酶的产生,并根据过夜培养后形成的粉红色区域确定活性。
Production of L-Aparaginase by Using Pectobacterium carotovorum
L-Asparaginase appears to be highly effective especially in children with newly diagnosed Acute lymphoblastic leukemia. Prolonged L-Asparaginase intensification improved the outcome significantly. Nowadays L-Asparaginase is an essential drug that is used to treat children with Acute lymphoblastic leukemia all over the world. Its potential is now well established, as it has remarkably induced remission in most of the patients suffering with this disease. This therapy has brought a major breakthrough in modern oncology and with the development of its new functions, a great demand for L-Asparaginase is expected in the coming years. Keeping the potential of this particular enzyme in cancer treatment, the present work is planned with an intention of optimizing the production of L-Asparaginase both by conventional as well as by genetic engineering techniques. Pectobacterium carotovorum is selected for the present work based on its potentiality in cancer treatment and due to less glutaminase activity compared to the enzyme sourced from E. coli. Microbial culture was procured from MTCC, Chandigarh and screened for L-Asparaginase production in plate method and identified the activity based on the formation of pink color zone after overnight incubation.
