Partially complements natural chromosomal DNA transformation defect of an H.influenzae dprA disruption mutant (PubMed:16978360). May help load RecA onto ssDNA (By similarity). No visible effect on transformation or growth in the presence or absence of mitomycin C (in strain KA797), on plasmid conjugation (in strain PC4020), on nucleotide excision repair, survival of UV damage or DNA recombination (PubMed:16978360). Belongs to the DprA/Smf family.
