Genetic analysis of an invasion region by use of a Tn3-lac transposon and identification of a second positive regulator gene, invE, for cell invasion of Shigella sonnei: significant homology of invE with ParB of plasmid P1.

Abstract excerpt

We have previously cloned two distinct regions of the Shigella sonnei form I plasmid pSS120, a 37-kilobase-pair DNA region and a virF region, which were found to be essential for cell invasion in Escherichia coli K-12 (J. Kato, K. Ito, A. Nakamura, and H. Watanabe, Infect. Immun. 57:1391-1398, 1989). The 37-kilobase-pair DNA region was randomly inserted by use of transposon Tn3-lac. At least eight genes were...
