Webb12 feb. 2016 · Homologous recombination provides a mechanism of DNA double-strand break repair (DSBR) that requires an intact, homologous template for DNA synthesis. … Webb31 juli 2003 · Since the homologous recombination protein RecG also promotes rescue of replication forks that are stalled at damaged DNA (McGlynn and Lloyd 2002; Sharples et al. 1999; Singleton et al. 2001), our results provide indirect evidence that the mechanisms of helicase-mediated resistance may be via DNA replication-repair.

Dynamics of the Interaction of RecG Protein With Stalled

WebbCoupled with the reported pleiotropy of recG mutations, this broad range of potential targets has made it hard to pin down what the protein does in vivo, though roles in recombination and replication fork repair have been suggested. However, recent studies suggest that RecG provides a more general defence against pathological DNA replication. Webb29 apr. 2015 · Abd Wahab, S., Choi, M. & Bianco, P. R.

Homologous recombination repair is a DNA repair process that includes the invasion of an undamaged DNA molecule by a damaged molecule of … WebbThe RecG of Escherichia coli is needed for normal levels of recombination and for repair of damaged DNA. RecG homologues are found in most bacterial species [4] . Strains carrying mutations in this gene show reduced recombination in conjugational crosses and increased sensitivity to UV, mitomycin C and ionizing radiation [5] , [6] , [7] . cheerleading netherlandsWebb19 mars 2004 · This suggests that RecG has an important role in the repair of forks that encounter stalled RNA polymerase complexes. When bacterial cells are starved, there is a transient induction of the SOS response that helps bring about the genome-wide hypermutation called adaptive mutation. flavouring examples

"WebbRecG is a monomeric double-stranded DNA translocase that unwinds a variety of branched DNA molecules in vitro, including Holliday junctions, D-loops, R-loops and various models of replication forks (Lloyd and Sharples 1993; Whitby et al. 1993; Vincent et al. 1996; Fukuoh et al. 1997; McGlynn et al. 1997; Whitby and Lloyd 1998; McGlynn and Lloyd … " - Recg repair
