Transcriptional organization, regulation and role of the Porphyromonas gingivalis W83 hmu haemin-uptake locus

30 Oct 2006

Abstract excerpt

Porphyromonas gingivalis, an oral bacterium associated with periodontal disease, requires haemin for growth. Although several multigenic clusters encoding haemin-uptake systems are present on the genome of P. gingivalis, little is known regarding their transcriptional organization and expression. This study identified a 23 kDa iron-regulated haemin-binding protein encoded by a larger than previously reported...
