Table 2. Highly expressed ORFs under non-nitrogen fixing conditions. Annotated ORFs that show a more than 2-times higher expression level under non-nitrogen fixing than under nitrogen fixing conditions (the values are negative because nitrogen fixation was taken as reference). All ORFs annotated as putative, hypothetical, or unknown have been omitted. The key for metabolic classes can be found in Table 1.
