Protein that helps load RecA onto ssDNA during transformation (PubMed:17803906, PubMed:25138221). Binds cooperatively to circular ssDNA, is able to bridge different segments of DNA (PubMed:17803906). Favors the loading of RecA onto SsbA- or SsbB-coated ssDNA and formation of RecA-DNA filaments (PubMed:25138221). RecA-ATP cannot catalyze homologous DNA strand exchange; SsbA and DprA activate strand exchange by RecA-ATP (PubMed:25138221). Interacts with RecA (PubMed:17803906). Localizes mostly to the cell poles during the development of competence (PubMed:17630974). During competence a number of proteins (at least CoiA, ComFA, ComGA, DprA, RecA and SsbB) are thought to colocalize at the cell pole, in a disruption of ssbB DprA no longer accumulates (PubMed:17630974). Preferentially expressed in cells competent for DNA transformation; that is 5-15% of the population (PubMed:17630974). Expression activated by ComK (PubMed:11918817, PubMed:11948146). Transformation efficiency drops 50- to 100-fold (PubMed:11918817, PubMed:11948146). Belongs to the DprA/Smf family.
