Interspecies regulation of virulence through gingipain inhibition by a Tannerella forsythia serpin.
Periodontitis is driven by dysbiotic microbial communities in which Porphyromonas gingivalis (Pg) acts as a keystone pathogen through its caspase-like fold (Clan CD) proteases, gingipains. Tannerella forsythia (Tf), another member of the periodontal pathogenic community, uniquely produces the broad-spectrum serpin term...
