L-asparaginase is a clinically approved bacterial therapeutic enzyme widely used in the treatment of Acute Lymphoblastic Leukaemia and Lymphosarcoma. In this study, periplasmic L-asparaginase producing bacteria were isolated from forest soil. The enzyme coding region (ansB gene) was amplified from the most productive isolate Bacillus megaterium PHB29, using group specific primers. The gene was cloned in pGEMT Easy vector and sequenced using automated DNA sequencer. The phylogeny of the gene was studied and compared with related sequences from NCBI public database. The secondary structure of the gene was analysed with SOPMA software. The antigenicity of the protein was predicted and compared with other commercially available enzymes using semi-empirical method. The present study indicates that soil bacteria are a promising source of commercially and therapeutically important drugs which are still unexplored.
