Restriction of the activity of the recombination site dif to a small zone of the Escherichia coli chromosome.

Abstract:

:The recombination site dif is the target on the Escherichia coli chromosome of the site-specific recombinases XerC and XerD. The dif/XerC-D system plays a role during the cell cycle, probably by favoring sister chromosome monomerization or separation. A phenomenon of regional control over dif activity, also analyzed in this issue, is demonstrated here by translocation of dif to a series of loci close to the normal locus. We found that the site is physiologically active only within a narrow zone around its natural position. Competence for dif activity does not depend on the sequence of the normal dif activity zone (DAZ), because delta(dif) deletions larger than the DAZ result in Dif+ bacteria when dif is reinserted at the junction point. Although dif maps where replication normally terminates, termination of replication is not the elicitor. A strain with a large inversion that places dif and its surrounding region close to oriC remains Dif+, even when a Tus- mutation allows replication to terminate far away from it. Preliminary data suggest the possibility that specialized sequences separate the competent zone from the rest of the chromosome. We suspect that these sequences are members of a set of sequences involved in a polarized process of postreplicative reconstruction of the nucleoid structure. We propose that this reconstruction forces catenation links between sister chromosomes to accumulate within the DAZ, where they eventually favor recombination at dif.

  • Fos-Jun interaction: mutational analysis of the leucine zipper domain of both proteins.

    abstract::Jun and Fos oncoproteins form a complex that regulates transcription from promoters containing AP-1 binding sites. The 'leucine zipper' domain of both Fos and Jun is necessary for the formation of the heterodimer, but the role of specific leucine residues is unclear.
