Has bactericidal activity against some Gram-positive bacteria. Alpha-amino of Asn-1 is covalently linked with the carboxyl of Gly-34 to form a cyclopeptide (By similarity). Thioether cross-links are formed between cysteines and the alpha-carbons of other amino acids, Cys-7 to Thr-28 and Cys-13 to Phe-22 (By similarity). In forming this cross-link, Thr-28 is converted to D-amino acid (By similarity). Belongs to the bacteriocin class V family.
