Amino-acid sequences of a novel nisin variants deduced by the sequencing of nisin region from nine Lactococcus spp. strains obtained from raw goat milk and compared to the sequences of nisin A, Z, Q, F and U. The leader peptide is composed by 23 amino-acids, followed by amino-acids representing the mature peptide. Amino-acids highlighted in grey indicate variations when compared to the nisin A (the first nisin variation to be discovered) references. The complete amino-acid sequencesfrom the 9 wild strains have been deposited in GenBank (accession numbers KF146295 to KF146303, respectively).
