TL;DR: A triple mutant constructed in this study exhibited no hemagglutination using sheep erythrocytes or hemoglobin binding activity, as determined by a solid-phase binding assay with horseradish peroxidase-conjugated human hemoglobin, indicating that the adhesin domains seem to be particularly important for P. gingivalis cells to agglutinate ery Throcytes and bind Hemoglobin, leading to heme acquisition.

TL;DR: The Escherichia coli recQ gene, a member of the RecF recombination gene family, was set in an overexpression plasmid, and its product was purified to near-homogeneity as mentioned in this paper.

TL;DR: Findings indicate that the mobile genetic elements have been deeply involved in the extensive genome rearrangement of P. gingivalis and the occurrence of many of the strain-specific CDSs, which are frequently associated with genomic rearrangements.

TL;DR: A new mutation (recQ1) located between corA and metE on the standard linkage map was found to result in increased sensitivity to ultraviolet light and deficiency in conjugational recombination when placed in the recBC sbcB background, indicating that it blocked the RecF pathway of recobbination.

TL;DR: In this article, the authors demonstrate that Arg-gingipain makes a significant contribution to the virulence of Porphyromonas gingivalis, indicating that a major part of the hemagglutinin activity of the organism is associated with the two genes.
