To combat nutritional immunity, N. gonorrhoeae has evolved systems to hijack zinc and other metals directly from host metal-binding proteins such as calprotectin (CP). Here, we report the 6.1 Å cryoEM structure of the gonococcal surface receptor TdfH in complex with a zinc-bound CP tetramer. We further show that TdfH can also interact with CP in the presence of copper and manganese, but not with cobalt. 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.
