Cooperative binding of polyamines induces the Escherichia coli single-strand binding protein-DNA binding mode transitions.


The Escherichia coli single-strand binding (SSB) protein is an essential protein involved in DNA replication, recombination, and repair processes. The tetrameric protein binds to ss nucleic acids in a number of different binding modes in vitro. These modes differ in the number of nucleotides occluded per SSB tetramer and in the type and degree of… (More)
