FIG. 2.
DNA sequences of the K. aerogenes put regulatory region and challenge phages. The wild-type K. aerogenes put regulatory region and DNA sequences from the wild-type K. aerogenes put regulatory region present in challenge phages SD1-1, SD2-1, SH4-1, and SH26-10 are shown. The sequence of the put DNA is shown in capital letters. The adjacent sequences in the challenge phage are shown in lowercase letters. Note that the substitution is inverted in challenge phage SD2-1 versus SD1-1 and SH4-1 versus SH26-10. Underlined nucleotides represent the −10 and −35 region of Pant.
