Homologous Strand Exchange and DNA Helicase Activities in Plant Mitochondria
… organisms by exchange and rearrangement of DNA. Most of our knowledge about homologous recombination is limited to processes in bacteria or in eukaryotic nuclei. In E. coli, homologous recombination is dependent on the RecA protein. Higher plant chloroplasts have RecA-like strand exchange …

Single molecule force spectroscopy of single stranded DNA binding protein and Rep helicase
Single-stranded DNA binding (SSB) proteins are essential accessory proteins that protect single-stranded DNA (ssDNA) during genome maintenance. Escherichia coli SSB is a prototypical homo-tetrameric SSB protein that can wrap up to 65 nucleotides of ssDNA in one of its binding modes. Here we present …

Binding configurations of single-stranded DNA binding protein and their influence on DNA recombinase
DNA inside a cell is continuously damaged through multiple mechanisms including environmental exposure to radiation, chemical agents, or UV light. Certain products of the cell's own metabolism, such as reactive oxygen species, can also damage the DNA. In the worst-case scenario, this damage results …
