- <p>Type IX secretion system (T9SS) <span> </span>has been studied mainly in Porphyromonas gingivalis. Among the 18 genes, essential for T9SS function, a group of four, porK-L-M-N<span> </span>belongs to a co-transcribed operon that expresses the T9SS core membrane complex. The central component of this complex, PorM (or GldM), is anchored in the inner membrane by a trans-membrane helix and interacts through the outer membrane PorK-N complex. There are available atomic structures</p> <p>PorM complex. Here we report the AlphaFold2 predicted structure of several complexes involving PorK-L-M-N:</p> <ul> <li>A dimer of<span> </span>PorK-PorN</li> <li>A ring of the PorK-PorN complex</li> <li>The PorM dimer in complex with the PorL pentamer,</li> <li>PorK in complex with the PorMd1-3 dimer.</li> </ul>
