E. coli DNA Ligase catalyzes the formation of a phosphodiester bond between the 5′-phosphate and the 3′-hydroxyl of two adjacent DNA strands in duplex DNA with cohesive ends. It is not appreciably active on blunt-ended substrates. E. coli DNA Ligase uses NAD as a cofactor and can be heat-inactivated. E. coli DNA Ligase is active at a range of temperatures (4Â°C – 37Â°C).

E.coli SSB

E. coli SSB (single-stranded binding) protein is a single-stranded DNA (ssDNA) binding protein essential for E. coli DNA replication and repair. The tetramer formed by the SSB protein specifically binds 8-16 nucleotides, thereby protecting ssDNA from nuclease degradation. In vitro experiments have shown that this protein can stabilize single-stranded regions of DNA, thereby relaxing double-stranded regions, which enhances the activity of DNA polymerase.
