Fig 1.
Nucleotide sequence of the mupB gene and its promoter region. Start and stop codons are indicated in bold, and protein translation is reported above the DNA sequence. A putative promoter region is indicated, including the −35 box (TTGAAA), the −10 box (ATTAAT), and a ribosome binding site (RBS) (AAGGAAG). Conserved motifs found in class I tRNA synthetases are highlighted in gray.
