Abstract

ABC transporters present great medical and pharmaceutical relevance since they are related to the development of the phenomenon of multiple drug resistance (MDR) in the treatment of cancer, bacterial resistance, infectivity and pathogenesis. Although extensively studied in many organisms, there are few functional or structural studies on these transporters in Mycobacterium tuberculosis and Xanthomonas citri pv. citri, two pathogenic bacteria studied by our group. In this project, different approaches will be developed to determine the function of these proteins in the mechanisms of pathogenesis and bacterial resistance, structural studies to understand mechanisms of interaction and ways of inhibiting the transporters.
