Specificity of E. coli K-12 chromosomal segment regulating the expression of systems inhibiting flac plasmid transfer

Specificity of E. coli K-12 chromosomal Thr-Leu-segment (genetic locus tis) regulating the expression of systems inhibiting Flac plasmid transfer is revealed. The findings point to a complex (polygenous) structure of this locus. ©1998 Plenum Publishing Corporation.
