Interactions of the site-specific recombinases XerC and XerD with the recombination site dif.
The Xer site-specific recombination system of Escherichia coli is involved in the stable inheritance of circular replicons. Multimeric replicons, produced by homologous recombination, are converted to monomers by the action of two related recombinases XerC and XerD. Site-specific recombination at a locus, dif, within the chromosomal replication terminus region is thought to convert dimeric chro...
متن کاملAction of site-specific recombinases XerC and XerD on tethered Holliday junctions.
In Xer site-specific recombination, two related recombinases, XerC and XerD, mediate the formation of recombinant products using Holliday junction-containing DNA molecules as reaction intermediates. Each recombinase catalyses the exchange of one pair of specific strands. By using synthetic Holliday junction-containing recombination substrates in which two of the four arms are tethered in an ant...
متن کاملDeterminants of selectivity in Xer site-specific recombination.
A remarkable property of some DNA-binding proteins that can interact with and pair distant DNA segments is that they mediate their biological function only when their binding sites are arranged in a specific configuration. Xer site-specific recombination at natural plasmid recombination sites (e.g., cer in ColE1) is preferentially intramolecular, converting dimers to monomers. In contrast, Xer ...
متن کاملThe XerC recombinase of Proteus mirabilis: characterization and interaction with other tyrosine recombinases.
XerC and XerD are two site-specific recombinases, which act on different sites to maintain replicons in a monomeric state. This system, which was first discovered and studied in Escherichia coli, is present in several species including Proteus mirabilis, where the XerD recombinase was previously characterized by our laboratory. In this paper, we report the presence of the xerC gene in P. mirabi...
متن کاملGenetic fate mapping using site-specific recombinases.
Understanding how cells are assembled in three dimensions to generate an organ, or a whole organism, is a pivotal question in developmental biology. Similarly, it is critical to understand how adult stem cells integrate into an existing organ during regeneration or in response to injury. Key to discovering the answers to these questions is being able to study the various behaviors of distinct c...
