Function

The seven competence proteins, ComB, ComP, PilV, PilX and FimT are absolutely essential for natural transformation. These proteins are hydrophilic and are similar to pilins, the structural subunits of type IV pili (T4P). The disruption of comB, comP and the deletion of pilV, pilX or fimT resulted in complete transformation deficiencies.
