To determine the binding partner(s) of PG27, we used a <jats:italic><jats:styled-content style=\"fixed-case\">P</jats:styled-content>orphyromonas gingivalis</jats:italic> mutant strain, 83K48, which expressed functional histidine‐tagged PG27. Purification of histidine‐tagged PG27 from 83K48 found that 136‐<jats:styled-content style=\"fixed-case\">kD</jats:styled-content>a and 264‐<jats:styled-content style=\"fixed-case\">kD</jats:styled-content>a proteins accompanied histidine‐tagged PG27. Mass spectrometry revealed the 136‐<jats:styled-content style=\"fixed-case\">kD</jats:styled-content>a protein and 264‐<jats:styled-content style=\"fixed-case\">kD</jats:styled-content>a protein to be PG0026 and PG1837 (HagA), respectively. PG0026 is a C‐terminal signal peptidase which cleaves the <jats:styled-content style=\"fixed-case\">CTD</jats:styled-content>s of other <jats:styled-content style=\"fixed-case\">CTD</jats:styled-content> proteins. A cross‐linking and a native electrophoresis studies suggested the interaction between histidine‐tagged PG27 and HagA and the interaction between histidine‐tagged PG27 and PG0026. We constructed <jats:italic><jats:styled-content style=\"fixed-case\">P</jats:styled-content>orphyromonas gingivalis</jats:italic> gene disrupting mutants, and characterized them. PG0026 was required for the full activities of gingipains, whereas HagA was not. A mutation disrupting <jats:italic>PG0026</jats:italic> affected localization of PG27, but a mutation disrupting <jats:italic>PG1837</jats:italic> showed little effect on the expression and localizations of PG27 and PG0026. To determine the functional role of HagA, we used <jats:italic>PG1837</jats:italic>‐disruptant 83K54 which expressed functional histidine‐tagged PG27. Histidine‐tagged PG27 in 83K54 was co‐purified with not only PG0026 but also several contaminated proteins. These results suggest that PG0026 interacts with PG27 in the absence of HagA, and that the binding state of a PG27‐PG0026 complex was affected and stabilized by HagA. Taken together, these data suggest that secreted PG0026 anchors to the cell by interacting with PG27, is stabilized by HagA, and functions in processing of other CTD proteins such as gingipains.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004235807910788","@type":"Researcher","foaf:name":[{"@value":"K.
