Research Abstract

We found that CTD proteins in Porphyromonas gingivalis are secreted onto the cell surface via the Por secretion system and the CTD region are processed when the proteins are bound to A-LPS. In addition, we identified the Wzz, Wzx, and WbaP proteins that are involved in the LPS biosynthesis in P. gingivalis.
