UniProtKB - P0A2P7 (XERD_SALTI)
Protein
Tyrosine recombinase XerD
Gene
xerD
Organism
Salmonella typhi
Status
Functioni
Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. Binds cooperatively to specific DNA consensus sequences that are separated from XerC binding sites by a short central region, forming the heterotetrameric XerC-XerD complex that recombines DNA substrates. The complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids. In the complex XerD specifically exchanges the bottom DNA strands (By similarity).By similarity
Activity regulationi
FtsK may regulate the catalytic switch between XerC and XerD in the heterotetrameric complex during the two steps of the recombination process.By similarity
