Disease relevance of ruvC

 

High impact information on ruvC

 

Biological context of ruvC

  • Multicopy plasmids expressing RusA alone make ruvA, ruvB, and ruvC mutants resistant to UV light [8].
  • The product of the ruvC gene, which is not regulated by the SOS system, resolves Holiday junctions by introducing nicks at or near the crossover junction in strands with the same polarity at the same sites [9].
  • To probe the validity of the E. coli paradigm, we examined the impact of mutations in DeltaruvAB and DeltarecU (a ruvC functional analog) on DNA repair [2].
  • Two further open reading frames of unknown function were identified, one on either side of the orf-33-ruvC operon [10].
  • The ruvC gene of Escherichia coli specifies a nuclease that resolves Holliday junction intermediates in genetic recombination (B. Connolly, C.A. Parsons, F.E. Benson, H.J. Dunderdale, G.J. Sharples, R.G. Lloyd, and S.C. West, Proc. Natl. Acad, Sci. USA 88:6063-6067, 1991) [10].
