Protein

Crossover junction endodeoxyribonuclease RusA

Gene

rusA

Organism
Aquifex aeolicus (strain VF5)
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.1 Publication

Catalytic activityi

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

Cofactori
