Protein
Crossover junction endodeoxyribonuclease RusA
Gene
rusA, Z1873, ECs1619
Organism
Escherichia coli O157:H7
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Endonuclease that resolves Holliday junction intermediates made during homologous genetic recombination and DNA repair. Exhibits sequence and structure-selective cleavage of four-way DNA junctions, where it introduces symmetrical nicks in two strands of the same polarity at the 5' side of CC dinucleotides. Corrects the defects in genetic recombination and DNA repair associated with inactivation of RuvAB or RuvC By similarity.

Catalytic activityi

Endonucleolytic cleavage at a junction such as a reciprocal single-stranded crossover between two homologous DNA duplexes (Holliday junction).

Cofactori

Binds 1 magnesium ion per subunit By similarity.
