Phage VP882 possesses quorum-sensing-driven lytic induction and stress-mediated host growth suppression mechanisms

Grace A. Beggs, Bonnie L. Bassler

This paper identifies two pathways in phage VP882: quorum-sensing-driven lysis and stress-mediated host growth suppression, with QtiQ inactivating a complex that causes growth arrest.

Molecular basis of quorum-sensing signal transduction by CqsS and its inhibition by CqsA the autoinducer synthase

Mengchan Liu, Yufan Yang, Julie S. Valastyan…·Hongwu Qian

This study determines the cryo-EM structures of CqsS and its interaction with CqsA and CAI-1, revealing the molecular mechanism of quorum-sensing signal transduction in Vibrio harveyi.
