YtnP, N-acyl homoserine lactonase from Bacillus subtilis WB600

YtnP encodes for an N-acyl homoserine lactonase in B. subtilis WB600. This enzyme catalyzes the hydrolysis of N-Acyl homoserine lactone (AHL) (Schneider et al., 2012).

Usage and Biology

YtnP degrades AHLs, a class of signaling molecules that induce quorum sensing. Quorum sensing triggers the expression of virulence factors in pathogens, including Aeromonas hydrophila, an aquatic bacterium that threatens aquaculture (Coquant et al., 2020; Hlordzi et al., 2020). High expression of YtnP in the probiotic B. subtilis reduces the virulence of A. hydrophila through quorum quenching and saves aquatic animals.
