Structural Characterization of the Lactoferrin Receptor from Neisseria meningitidis

摘要

The meningococcal lactoferrin receptor is composed of the integral outer membrane protein LbpA and the peripheral lipoprotein LbpB. Homooligomeric complexes of LbpA and heterooligomers consisting of LbpA and LbpB were identified. Furthermore, five cell surface-exposed loops of LbpA were identified, which partially confirms a previously proposed topology model.
