Our current research centers in the structural and functional characterization of cell-envelop protein factors playing key processes in M. tuberculosis’ virulence and life cycle. For this purpose, we use a multi-disciplinary approach combining Molecular Biology, Protein Engineering, and Structural Biology techniques. Our strategy implies the recombinant production of those protein factors and determining their three-dimensional structure using X-Ray Crystallography.
​
Structural information is further complemented and validated using other molecular biology and biophysical studies. Altogether this enables us to obtain detailed information about how these macromolecules function at a molecular level and thus, to acquire a deep understanding of their biological function and role in pathogenesis. Moreover, our aim is using this knowledge to develop molecules with biotechnological interest, such new antimicrobials.
