Structural Microbiology - Pedro ALZARI

Activities of the Unit

Our research activities in structural microbiology are focused on the molecular characterization of bacterial signaling and regulation processes, using crystallographic, biophysical and biochemical approaches. Our main research projects include the molecular studies of signaling pathways mediated by eukaryotic-like protein kinases in Mycobacterium tuberculosis, the structure and function of bacterial two-component systems, and the regulation mechanisms of lipid biosynthesis in Gram-positive pathogenic bacteria.
