Organism

Rickettsia bellii (strain RML369-C) [Complete proteome] [HAMAP]

Taxonomic identifier

336407 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia

Protein attributes

Sequence length	305 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. The xerC-xerD 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 By similarity. HAMAP MF_01808
Subunit structure	Forms a cyclic heterotetrameric complex composed of two molecules of xerC and two molecules of xerD By similarity.
Subcellular location	Cytoplasm By similarity HAMAP MF_01808.
Sequence similarities	Belongs to the 'phage' integrase family. XerC subfamily.
