Identification of the iroA gene product of Neisseria meningitidis as a lactoferrin receptor.

摘要

The iroA gene product is an iron limitation-inducible outer membrane protein of Neisseria meningitidis. A spontaneous mutant lacking the gene was unable to bind lactoferrin. Furthermore, Escherichia coli strains expressing the IroA protein were capable of binding lactoferrin. Apparently, the IroA protein functions as a lactoferrin receptor.
