The DNA single-strand break (SSB) repair pathway is initiated by the multifunctional enzyme PARP-1, which recognizes the broken DNA ends by its two zinc-finger domains, Zn1 and Zn2. Despite a number ...
Single-stranded DNA-binding proteins (SSBs) protect transiently exposed ssDNA, yet how DNA polymerase (DNAp) displaces them during replication remains unclear. Using single-molecule force spectroscopy ...
