Defining the role of Hmu and Hus systems in Porphyromonas gingivalis heme and iron homeostasis and virulence

Abstract excerpt

Iron and heme are essential nutrients for all branches of life. Pathogenic members of the Bacteroidota phylum, including Porphyromonas gingivalis, do not synthesize heme and rely on host hemoproteins for heme as a source of iron and protoporphyrin IX. P. gingivalis is the main pathogen responsible for dysbiosis in the oral microbiome and the initiation and progression of chronic periodontitis. It utilizes Hmu and...
