Abstract

In this study, we chose to target the Isocitrate Lyase 1(ICL-1) gene as a possible target for the treatment of tuberculosis. We took this approach because ICL-1 allows the Mycobacterium tuberculosis bacteria to skip some of the steps in the KREBS cycle, which gives it the ability to survive in low-oxygen environments. The ICL-1 gene found in M. tuberculosis was amplified using PCR to prepare an expression system for testing drugs targeting the ICL-1 protein. In order to do this, primers were designed to clone the gene and give it restriction sites, which allowed us to insert the ICL-1 gene insert into a vector, and finally into E. coli cells. Since this work is still in progress, an expression vector containing ICL-1 was acquired and transformed into BL21 DE3. Protein was subsequently expressed and purified.
