Function
Lanthionine-containing peptide antibiotic (lantibiotic) active on Gram-positive bacteria. The bactericidal activity of lantibiotics is based on depolarization of energized bacterial cytoplasmic membranes, initiated by the formation of aqueous transmembrane pores. Ruminococcin A is a broad spectrum bacteriocin exhibiting activity against a wide range of pathogenic clostridia and B.longum (By similarity).
