FIG. 3.

Coding sequence of the 3,960-bp region comprising a part of the purH gene, the complete SsuDAT1I genes, and a part of the purD gene. The deduced amino acid is indicated underneath the first nucleotide of each codon in the coding sequence. Arrows underneath the nucleotide sequence, positions of the primers used for the amplification and cloning of the restriction and modification genes; bent arrows, terminal ends of the cloned fragments of plasmids pDAM3, pDAM4, pDAM7, pDAM9, and pDAM10; lines above the sequence, sequences resembling a combox, the second Shine-Dalgarno sequence (S.D.), and the second start codon in the ssuMB gene. The coding sequence shown corresponds to nucleotides 3901 to 7860 of the sequence with accession no. AB045609.
