Two main types of two-component systems (TCSs) are responsible for lantibiotic resistance: the Bce-like TCSs (A) and the Lia-like TCSs (B). The presence of antimicrobials, such as lantibiotics, or the cell damage incurred as a result of their presence causes these TCSs to mediate the transcription of genes whose products confer a resistance phenotype.
