Protein domain family PF09905 (DUF2132) is a family of small domains of unknown function that are conserved in a wide range of bacteria. Here we describe the solution NMR structure of the 80-residue VF0530 protein from Vibrio fischeri, the first structural representative from this protein domain family. We demonstrate that the structure of VF0530 adopts a unique four-helix motif that shows some similarity to the C-terminal double-stranded DNA (dsDNA) binding domain of RecA, as well as other nucleic acid binding domains. Moreover, gel shift binding data indicate a potential dsDNA binding role for VF0530.
