FIGURE 6.
Model of the inhibitory mechanism of ApoLp against SaeS through binding to LTA. Binding of ApoLp to LTA inactivates the SaeS sensor kinase. The extracellular domain of SaeS is essential for recognizing the binding of ApoLp to LTA. The magenta arrows indicate possible pathways for the physical alteration of LTA that leads to inactivation of SaeS.
