Comments Information
Function
- Lanthionine-containing peptide antibiotic (lantibiotic) Transiently and partially depolarizes the transmembrane electrical potential and pH gradient of susceptible cells, inhibits the uptake of amino acids and depletes the intracellular ATP pool.
PTM
- Maturation of lantibiotics involves the enzymic conversion of Thr, and Ser into dehydrated AA and the formation of thioether bonds with cysteine. This is followed by membrane translocation and cleavage of the modified precursor.
