Neisseria gonorrhoeae bacterioferritin: structural heterogeneity, involvement in iron storage and protection against oxidative stress.

Microbiology (Reading, England) - 1 Oct 1999

Chen C Y, Morse S A

Abstract excerpt

The iron-storage protein bacterioferritin (Bfr) from Neisseria gonorrhoeae strain F62 was identified in cell-free extracts and subsequently purified by column chromatography. Gonococcal Bfr had an estimated molecular mass of 400 kDa by gel filtration; however, analysis by SDS-PAGE revealed that it was composed of 18 kDa (BfrA) and 22 kDa (BfrB) subunits. DNA encoding BfrB was amplified by PCR using degenerate...
