Function
Suggested to be the precursor for an exported, modified peptide that has antimicrobial and/or signaling properties. Synthesis requires YydG and YydH; the peptide is proposed to be exported by the YydIJ transporter. In the absence of the transporter, the modified peptide activates the LiaRS two-component regulatory system, possibly by eliciting cell envelope stress. This activation can occur in trans in cocultured cells lacking either the transporter or the whole operon.
