Abstract excerpt
In a search for Proteus mirabilis genes that were regulated by cell-to-cell signalling, a lacZ fusion (cmr437::mini-Tn5lacZ) was identified that was repressed 10-fold by a self-produced extracellular signal from wild-type cells. However, the cmr437::mini-Tn5lacZ insertion itself led to a marked reduction in this extracellular repressing signal. The cmr437::mini-Tn5lacZ insertion was mapped to a speA homologue in...
