HmbR, a hemoglobin-binding outer membrane protein of Neisseria meningitidis, undergoes phase variation.

Journal of bacteriology - 1 Apr 1999

Richardson A R, Stojiljkovic I

Abstract excerpt

Neisseria meningitidis uses hemoglobin (Hb) as an iron source via two TonB-dependent outer membrane receptors, HmbR and HpuB. Analysis of 25 epidemiologically unrelated clinical isolates from serogroups A, B, C, and Y revealed that 64% strains possessed both Hb receptor genes. Examination of the hmbR expression pattern in strains in which the hpuB gene was genetically inactivated revealed two distinct Hb...
