xerH

Gene

xerH

Protein

Tyrosine recombinase XerH

Organism

Helicobacter pylori (strain ATCC 700392 / 26695)

Length

362 amino acids

Function

Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. Involved in chromosome segregation. May contribute to chromosome decatenation.

Similarity

Belongs to the 'phage' integrase family. XerH subfamily.

Mass

41.851 kDa
