RusA family crossover junction endodeoxyribonuclease
This family consists of several bacterial and phage Holliday junction resolvase (RusA) like proteins. The RusA protein of Escherichia coli is an endonuclease that can resolve Holliday intermediates and correct the defects in genetic recombination and DNA repair associated with inactivation of RuvAB or RuvC [1,2].

crossover junction endodeoxyribonuclease RusA
This HMM describes the founding member of the family, the crossover junction endodeoxyribonuclease RusA of the DLP12 prophage region in Escherichia coli K-12, and closely related proteins. More distantly related proteins should be called RusA family crossover junction endodeoxyribonuclease, not RusA per se.
