Stimulation of Escherichia coli DNA damage inducible DNA helicase DinG by the single-stranded DNA binding protein SSB

► Specific interaction between E. coli SSB and DNA helicase DinG was explored. ► SSB forms a protein complex with DinG and stimulates the DNA helicase activity. ► A mutant SSB that fails to interact with DinG inhibits the DNA helicase activity.
