Partial Characterization of Novel Bacteriocin SF1 Produced by Shigella flexneri and Their Lethal Activity on Members of Gut Microbiota

Figure 2

Amino acid sequence of bacteriocin SF1. The observed sequence is similar to the colicin U of S. boydii. Only in five positions of the sequence, the amino acid glutamine (Q) changes to glutamic acid (E) (grey highlighted).
