Fig. 3

Graphic representation of lactococcin 972 clusters III (a) and IV (b), respectively. Homologous genes in different samples are indicated by the same color. Square brackets point a part of the pld locus in S. mitis genomes in the bottom picture. Unfilled arrows mark the fragments of nucleotide sequences which are homologous to pld1-3 or pld4 genes (see text)
