NameruvABC Holliday junction complex
TypeSYSTEM
DescriptionRuvA, RuvB and RuvC proteins together act on Holliday junctions for homologous recombination and DNA repair. RuvAB is the branch migration complex and RuvC the resolvase. The system is strictly bacterial; proteins with little or no detectable sequence similarity process Holliday junctions in Archaea, eukaryotes, and some phage. A variety of Holliday junction-cleaving (Hjc) enzymes have been found in the Archaea (PMID:12382111). Holliday junction resolvases, including RuvC, Hjc and Hje, CCE1 (yeast) and A22R (poxviruses) are reviewed by Sharples (PMID:11251805). RuvC is replaced by RecU in firmicutes and mollicutes.
