Figure 6. Heme-stained membrane proteins from cells of B. japonicum wild type (WT; lanes 1 and 4), regR mutant strain 2426 (lanes 2 and 5), and regS mutant strain 2409 (lane 3) cultured in BSN medium under anoxic conditions or 2% initial O2.
About 20 µg membrane proteins were loaded per lane. Heme-stained c-type cytochromes identified previously are specified at the right margin along with their predicted mass. Note that all the samples were run in parallel on the same gel.
