[https://www.uniprot.org/uniprot/TBPB1_NEIMI TBPB1_NEIMI] Neisseria acquires iron by extracting it from serum transferrin (TF) in its human host. Acts as a TF receptor and is required for TF utilization. Involved in the initial capture of TF. Helps select only those TF molecules that can be used as an iron source and concentrates them on the cell surface, maintaining the iron-loaded status of the TF C-terminal lobe until its delivery to TbpA.<ref>PMID:22343719</ref>

== Publication Abstract from PubMed ==
 +
Neisseria meningitidis, the causative agent of bacterial meningitis, acquires the essential element iron from the host glycoprotein transferrin during infection through a surface transferrin receptor system composed of proteins TbpA and TbpB. Here we present the crystal structures of TbpB from N. meningitidis in its apo form and in complex with human transferrin. The structure reveals how TbpB sequesters and initiates iron release from human transferrin.
