Figure 2
(a) Deduced amino acid sequences of the region encoding nisin Z in Lactococcus lactis ID1.5, ID3.1, ID8.5, PR3.1, PD4.7, and homologous sequence of L. lactis NIZO 22186 obtained from the GenBank. (b) Alignment of the nisZ promoter sequences of L. lactis ID1.5, ID3.1, ID8.5, PR3.1, and PD4.7. The −35 and −10 sites and TCT-N8-TCT are underlined. (c) Alignment of the nisF promoter sequences of Lactococcus lactis ID1.5, ID3.1, ID8.5, PR3.1, and PD4.7. The −35 and −10 sites and TCT-N8-TCT are underlined.
