Expression of all5036 encoding the only TonB in Anabaena sp. PCC 7120. Anabaena sp. PCC 7120 were grown as for experiments shown in Figure 6 in BG11 (lane 1-4) or BG110 (lane 5-8) with and without a source of ferric ammonium citrate and/or copper and reverse transcription (RT) polymerase chain reaction was performed in the absence (-RT) or presence of reverse transcriptase on isolated RNA using primers for rnpB and all5036 (listed in Table 3) to visualize expression.
