Production of Brucella lumazine Synthase Recombinant Protein to Design a Subunit Vaccine against Undulant Fever

Brucella bacterium causes Brucellosis, an infectious disease spreading from animals to human. Brucella lumazine synthase (BLS) is a highly immunogenic protein with adjuvant properties, which has been introduced as an effective protein carrier for vaccine development. This protein also plays a significant role in inducing immune system. This study aimed to clone, express, and purify the BLS gene from Brucella melitensis Rev۱. The BLS gene was amplified by particular primers with the restriction enzyme sites as a linker and it was inserted into pTZ۵۷R/T vector. Subsequently, it was ligated into pET۳۲(a)+ expression vector. Recombinant expression vector containing coding sequence of BLS was transformed into E. coli BL۲۱ (DE۳) host gene expression and stimulated by ۰.۱mM IPTG. The results of sequencing showed that there were not any mutations in BLS encoding sequence. The expression results were set by sequencing and endorsed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analyses and western blotting that showed ۳۵ kDa protein band appropriately.
