The protein
Basic information/ Evolution
- Catalyzed reaction/ biological activity:
- the enzyme is functional as a heterodimer of the AddA and AddB subunits, that it is a rapid and processive DNA helicase, and that it catalyses DNA unwinding using one single-stranded DNA motor of 3'→5' polarity located in the AddA subunit PubMed
- the AddB subunit contains a second putative ATP-binding pocket, but this does not contribute to the observed helicase activity and may instead be involved in the recognition of recombination hotspot sequences PubMed
- Protein family: uvrD-like helicase C-terminal domain (according to Swiss-Prot)
