^aAttenuators were extracted from the website of Merino [66]. Links are provided for viewing the complete data, including a visualization of the putative attenuator structures.
^bThe symbol ^¬ is used for attenuators. Genes encoding the alternative biochemical steps that were recently reported for formation of dehydroquinate from aspartate semialdehyde and ketohexose 1-phosphate [52] are designated aroA' and aroB'.
^cRefers to figures within this manuscript or, if enclosed within parentheses, to the figure in ref. [7].
