It is interesting to note that the name 'Tol' derives from experiments which show that the ''tol'' mutant is tolerant to colicin action<ref name='Davies'>PMID: 1095546</ref>. | It is interesting to note that the name 'Tol' derives from experiments which show that the ''tol'' mutant is tolerant to colicin action<ref name='Davies'>PMID: 1095546</ref>. | ||

It has been shown that the regulation of Tol genes is linked to the cell envelope stability<ref name="Cascales">PMID: 17347522</ref>. In studies with E. coli, the ''tol-pal'' genes have been induced by RcsC in response to cell envelope stress<ref>PMID: 8821933</ref>. RcsC is a transmembrane sensor kinase, and along with the cytoplasmic response regulator RcsB, makes up the RcsBC regulatory system<ref>PMID: 16166540</ref>. RcsBC is involved in the regulation of ''cps'' genes which code for the biosynthsis machinery of a major component for the capsula, cholanic acid. | It has been shown that the regulation of Tol genes is linked to the cell envelope stability<ref name="Cascales">PMID: 17347522</ref>.
