2024年12月13日 · However, one exonuclease, SbcB, counterintuitively promotes NT in Vibrio cholerae. Here, through a systematic analysis of the distinct steps of NT, we show that SbcB …

Cultures of recBC sbcB (sbcC+) strains grow slowly, contain many inviable cells, and rapidly accumulate fast-growing variants due to mutation of sbcC. sbcC has been identified on …

1988年11月15日 · We report here that mutation of a single gene, namely sbcC, can overcome this inviability and allow for the stable propagation of a 571-bp nearly perfect palindrome in …

2006年11月1日 · Most previous genetic studies of the RecF pathway were performed with recBC sbcB sbcC (D) strains carrying the sbcB15 suppressor mutation. sbcB15 belongs to the first …

2007年10月26日 · To assess the contributions of single-strand DNases (ssDNases) to recombination in a recBCD+ background, we studied 31 strains with all combinations of null …

2012年4月1日 · We show that in Δ recBCD Δ sbcB sbcC201 strains, recombination requires exclusively the RecQ helicase. In Δ recBCD sbcB15 sbcC201 strains, RecQ may be partially …

2001年10月29日 · Genetic analysis presented in this work revealed that the Δ ruvABC mutation causes an identical DNA repair defect in UV-irradiated recBC sbcBC, sbcBC, and sbcB …

Cultures of recBC sbcB (sbcC+) strains grow slowly, contain many inviable cells, and rapidly accumulate fast-growing variants due to mutation of sbcC. sbcC has been identified on …

The indirect suppression of recB (-) and recB (-)recC (-) mutations by the sbcB (-) allele is caused by the loss of a nuclease active on denatured DNA. Results from enzyme purifications and …

2002年3月1日 · In the present work, we show that the combination of sbcCD and sbcB null mutations renders the rep recBC strain viable by allowing the RecF pathway of recombination …
