Although the exact function of TolA is not yet known, it has been shown that unlike mutations in the proteins of the TonB system to which the TolQRA proteins show many similarities, mutations in the TolQRA proteins affect the outer membrane integrity.  TolA could be involved structurally by bringing the inner and outer membranes together and forming a bridge or link between them.<ref name='Sharyn'>PMID: 8416897</ref>
