Single-Stranded DNA-Binding Protein/SSB

Ambient

Recombinant E. coli Single-Stranded DNA-Binding Protein/SSB is produced with our E. coli expression system. The target protein is expressed with sequence (Met1-Phe178) of E. coli SSB.

Single-Stranded DNA-Binding Protein (SSB) is an essential protein that is present in all organisms ranging from viruses to humans, except Thermoproteales. It is a homotetramer, with each monomer containing one SSB domain. SSB is involved in DNA replication, recombination, & repair. This protein is essential for the replication of the chromosomes & its single-stranded DNA phages. SSB binds to single-stranded regions of DNA to prevent premature annealing, to protect the single-stranded DNA from being digested by nucleases, & to remove secondary structure from the DNA to allow other enzymes to function effectively upon it.
