Q3YZH8 - RUSA_SHISS

Protein

Crossover junction endodeoxyribonuclease RusA

Gene

rusA

Organism
Shigella sonnei (strain Ss046)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi
  1. 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.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
