Outline of Final Research Achievements

Iron is a metal element essential for pathogenic bacteria, but the iron in host cells is tightly bound to proteins such as ferritin or transferrin. Under such circumstances, host heme could be a major source of iron. Some Gram-negative pathogens utilize an extracellular heme-binding protein called hemophore to satisfy their needs for iron. We elucidated heme transport in Pseudomonas aeruginosa, Yersinia pseudotuberculosis, and Eikenella corrodens by spectroscopic and crystallographic methods.
