The human defense mechanism against pathogens involves limiting essential nutrients, such as zinc which is countered by surface receptor TdfH pirating zinc from human calprotectin. The TdfH cryo-EM structure from N. gonorrhoeae in complex with a calprotectin tetramer provides insights into the protein-protein interaction and the role of metal ions.
