FIG. 2.

φYeO3-12 promoters. In the upper part of the figure the 15 putative promoter sequences of φYeO3-12 are aligned and a consensus sequence is presented. The positions of the first nucleotides of the promoter sequences in the phage genome are given as well as the number of mismatches (indicated by uppercase letters) to the consensus sequence and the name of the promoter. Residues likely to determine the promoter specificity are in boldface type. In the lower part of the figure is an alignment of the consensus promoter sequences of φYeO3-12, T3, T7, K11, and SP6. Sequences of the nontemplate strand are presented; the transcription start site is at +1. Conserved nucleotides, when compared against the φYeO3-12 promoter are indicated by vertical bars.
