| Short Name | DprA_WH |
| description | This winged helix domain is found in the DprA protein [].DprA is a new member of the recombination-mediator protein family, dedicated to natural bacterial transformation []. In Helicobacter pylori, DprA is required for natural chromosomal and plasmid transformation []. It has now been shown that DprA binds cooperatively to single-stranded DNA (ssDNA) and interacts with RecA. In the process, DprA-RecA-ssDNA filaments are produced and these filaments catalyse the homology-dependent formation of joint molecules. While the Escherichia coli SSB protein limits access of RecA to ssDNA, DprA alleviates this barrier []. DprA has a role not only in ensuring production of transformants via interaction with RecA, it is also involved in competence shut-off via interaction with ComE []. |
