N -Acyl- l -Homoserine Lactone-Mediated Regulation of the Lip Secretion System in Serratia liquefaciens MG1

Abstract
The analysis of Serratia liquefaciens MG1 ′ luxAB insertion mutants that are responsive to N -butanoyl- l -homoserine lactone revealed that expression of lipB is controlled by the swr quorum-sensing system. LipB is part of the Lip exporter, a type I secretion system, which is responsible for the secretion of extracellular lipase, metalloprotease, and S-layer protein.
