Background: Silkworm ApoLp protein binds S. aureus cell surfaces and inhibits hemolysin gene expression. Results: ApoLp protein binds LTA. The ApoLp inhibitory effect was attenuated in an LTA synthetase knockdown mutant. Conclusion: ApoLp protein suppressed S. aureus virulence via LTA binding. Significance: A non-protein macromolecule on the bacterial cell surface functions as a receptor in the bacterial signal transduction pathway.
