WebSynthesis-dependent strand annealing ( SDSA) is a major mechanism of homology-directed repair of DNA double-strand breaks (DSBs). Although many of the features of SDSA were first suggested in 1976, [1] the double-Holliday junction model proposed in 1983 [2] was favored by many researchers. WebRecA protein hydrolyzes ATP to ADP and inorganic phosphate at a modest rate. In phase 1, RecA filaments bound to ssDNA hydrolyze ATP with a rate (kcat) approaching 30 min −1. …
