Figure 13 From: Inter-genomic displacement via lateral gene transfer of bacterial trp operons in an overall context of vertical genealogy Comparison of trpL leader regions in species of coryneform bacteria and in a representative enteric bacterium. In the coryneform bacteria, the start codon for trpL is uncertain, and second start sites at an internal position for C. glutamicum and C. efficiens are indicated by black, vertical arrows.Back to article page
