DNA-binding domain of the RepE initiator protein of mini-F plasmid: involvement of the carboxyl-terminal region.

Journal of bacteriology - 1 Apr 1995

Matsunaga F, Kawasaki Y, Ishiai M, Nishikawa K, Yura T, Wada C

Abstract excerpt

The RepE initiator protein (251 residues) is essential for mini-F replication in Escherichia coli and exhibits two major functions: initiation of DNA replication from ori2 and autogenous repression of repE transcription. Whereas the initiation is mediated by RepE monomers that bind to the ori2 iterons (direct repeats), the autogenous repression is mediated by dimers that bind to the repE operator, which contains...
