Dr. Zeytuni’s lab studies bacterial secretions systems and membrane transportation. Bacterial secretion systems are essential membrane embedded protein machineries, enabling bacteria to obtain nutrients, communicate, protect against biological and chemical agents, as well as facilitate disease through the delivery of virulence factors. Dr. Zeytuni’s lab integrates structural biology techniques including cryo-EM and X-ray crystallography with biochemical, biophysical and genetic approaches to determine the structure and decipher the molecular mechanisms of these transport machineries.
