2KTN, 2KTO - PubMed Abstract: 
A novel synergetic lantibiotic pair, Lchalpha (3249.51 Da) and Lchbeta (3019.36 Da), termed lichenicidin VK21, was isolated from the producer strain Bacillus licheniformis VK21. Chemical and spatial structures of Lchalpha and Lchbeta were determined. Each peptide contains 31 amino acid residues linked by 4 intramolecular thioether bridges and the N-terminal 2-oxobutyryl group ...
