ジャーナル: Commun Biol / 年: 2022 タイトル: TdfH selectively binds metal-loaded tetrameric calprotectin for zinc import. 著者: Aloke K Bera / Runrun Wu / Simone Harrison / Cynthia Nau Cornelissen / Walter J Chazin / Nicholas Noinaj / 要旨: 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.
