K. Riedel et al., N-acyl-L-homoserine lactone-mediated regulation of the Lip secretion system in Serratia liquefaciens MG1, J BACT, 183(5), 2001, pp. 1805-1809
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 Li
p exporter, a type I secretion system, which is responsible for the secreti
on of extracellular lipase, metalloprotease, and S-layer protein.
