YbaV is a predicted periplasmic protein required for cell-to-cell plasmid transfer that has a C-terminal ComEA-like tandem helix-hairpin-helix putative DNA-binding domain and may sequester incoming DNA in the periplasm, suppressing transformation efficiency (Matsuda, 2012). ybaV is predicted to have a CRP-S promoter co-regulated by both Crp and Sxy (Cameron, 2006). YbaV is predicted to have a 25 aa type I signal peptide.
