From: The TyrA family of aromatic-pathway dehydrogenases in phylogenetic context
Context of gene organization for tyrA, profiled against the 16S rRNA tree of the domain Bacteria. pheA, hisH b, tyrA, and aroF are color coded. Lineages typified by complete dispersal of aromatic-pathway genes are indicated by "GENE DISPERSAL". Gmet refers to Geobacter metallireducens; Dace refers to Desulfuromonas acetoxidans; and Ddes refers to Desulfovibrio desulfuricans. Consensus gene organizations are shown for the alpha and beta divisions of the Proteobacteria. The gamma division is subdivided to yield consensus gene organizations for the upper- and lower-gamma (enteric lineage) organisms. Genes that are adjacent and share a common transcriptional direction appear to reside in operons (or supraoperons). Any white spacing indicates substantial separation of the gene clusters shown in the genome. Genes of special interest are color coded, other genes of aromatic biosynthesis are shown in gray and all other genes are shown in white.
