Visualization of DNA double-strand break repair in live bacteria reveals dynamic recruitment of Bacillus subtilis RecF, RecO and RecN proteins to distinct sites on the nucleoids.

Abstract excerpt

We have found that SMC-like RecN protein, RecF and RecO proteins that are involved in DNA recombination play an important role in DNA double-strand break (DSB) repair in Bacillus subtilis. Upon induction of DNA DSBs, RecN, RecO and RecF localized as a discrete focus on the nucleoids in a majority of cells, whereas two or three foci were rarely observed. RecN, RecO and RecF co-localized to the induced foci, with...
