ABSTRACT The periodontal pathogen Porphyromonas gingivalis secretes gingipains, highly hydrolytic proteases, to the cell surface or external environment via a type IX secretion system (T9SS). PorE is one of the T9SS component proteins essential for gingipain secretion. It consists of four domains: TPR, WD40, CRD, and OmpA_C‐like.
