Crystal Structure of Porphyromonas Gingivalis Peptidylarginine Deiminase: Implications for Autoimmunity in Rheumatoid Arthritis.
Ann.Rheum.Dis., 75:1255-, 2016

PubMed Abstract: Periodontitis (PD) is a known risk factor for rheumatoid arthritis (RA) and there is increasing evidence that the link between the two diseases is due to citrullination by the unique bacterial peptidylarginine deiminase (PAD) enzyme expressed by periodontal pathogen Pophyromonas gingivalis (PPAD). However, the precise mechanism by which PPAD could generate potentially immunogenic peptides has remained controversial due to lack of information about the structural and catalytic mechanisms of the enzyme.
