Single-stranded DNA-binding proteins prevent the strands from reannealing and protect each template until it is bound within the catalytic site of a DNA polymerase for replication. In some cases, a template can be generated by degradation of one strand of the double helix by enzymes known as...
Figure 7. Single-strand DNA-binding proteins of bacteria and eukaryotes. (a) Model of E. coli SSB tetramer-ssDNA complexes based on crystal structure information. SSB is a homotetramer of subunits (colored differently); each subunit has one OB fold. The SSB tetramer has two binding modes, ...

Single-stranded DNA-binding proteins (SSBs) play essential roles in DNA replication,recombinational repair,and maintenance of genome stability.In human,the major SSB,replication protein A (RPA),is a stable heterotrimer composed of subunits of RPA1,RPA2,and RPA3,each df which is conserved not ...
3National Center for Protein Science Shang- hai, 320 Yueyang Road, Shanghai 200031, China Human single-strand (ss) DNA binding proteins 1 and 2 (hSSB1 and 2) are components of the hSSB1/2-INTS3- C9orf80 heterotrimeric protein complex shown to participate in DNA damage response and maint...
Single-strand DNA (ssDNA)-binding proteins (SSBs) are ubiquitous and essential for a wide variety of DNA metabolic processes, including DNA replication, recombination, DNA damage detection and repair. SSBs have multiple roles in binding and sequestering ssDNA, detecting DNA damage, stimulating nuclease...
As a result, A3A-induced mutations are enriched at hairpin-forming regions of cancer genomes and show strand bias for replication intermediates. It is also possible that larger ssDNA binding proteins, like RNA Polymerase occlude A3A binding. In our in vitro transcription assay, a 99 kDa T7 ...
