FIG. 1.

Nucleic acid sequences and predicted amino acid sequences of mtbA, mtmC, mtmB, mtmP, and orf1 of the mtm operon from M. barkeri. The predicted amino acid sequences are shown in single-letter code directly below the second base of each codon. Position numbers are given to the left of each row of the sequence. Overlined bases represent the predicted promoter sequences. Symbols and abbreviations: ▪, transcript start site determined from primer extension; ∗, predicted stop codon; ▾, position of UAG in reading frame of mtmB; > and < (shown above bases included in repeat sequences), direction of the repeat (indicated by the direction of the arrow head); S/D, predicted Shine-Dalgarno sequence.
