pubmed:abstractText |
Production of virulence factors and secondary metabolites is regulated in the phytopathogen Erwinia carotovora by quorum sensing involving N-acylated homoserine lactone (AHL) signaling molecules. Non-hydrolyzable AHL analogues were synthesized and screened in vivo. The biological activity of each compound was correlated with its ability to bind Erwinia AHL receptor proteins (LuxR homologues) in vitro. There is an excellent correlation between carbapenem production in vivo and in vitro binding to CarR. However, no such correlation could be found between exoprotease production and analogue binding to EccR. Our data are consistent with the involvement of a third, as yet uncharacterized LuxR homologue.
