Figure 5From: Characterization of hemin-binding protein 35 (HBP35) in Porphyromonas gingivalis: its cellular distribution, thioredoxin activity and role in heme utilizationGrowth in hemin-containing BHI broth (0-48 h) and hemin-free BHI broth (after 48 h). Circle, 33277; square, KDP164 (hbp35 insertion mutant); diamond, KDP166 (hbp35 deletion mutant); X, KDP171 (hbp35+ complemented strain derived from KDP166).Back to article page
