FIG. 3.

DNA sequence of sodF and flanking regions from N. commune DRH1. Shown is the complete coding region of sodF, with the putative amino acid sequence (underlined) and the putative ribosome-binding site (boldface underlining). Sequences of primers used to amplify the original 475-bp sodF fragment from genomic DNA correspond to positions 768 to 787 (5′ to 3′) and 1192 to 1210 (3′ to 5′) and are underlined; compare the N-terminal amino acid sequence with that of the native protein (Fig. 1a), which shows a single discrepancy (E→D) at position 16 of the open reading frame.
