Binding of 6His-SUMO-RegA, 6His-SUMO-RegA_D68A and 6His-SUMO-RegA_A102S to the regulatory region of target genes involved in Fe(II) and ISC oxidation. EMSA with the regulatory region of the rus, cta, petI, reg, tet, cyo, hdr, doxII, and cyd operons, hdrB and sqr genes as well as with an internal fragment of the 16S rRNA gene from Thiomonas arsenitoxydans (rrs). 6His-SUMO-RegA, 6His-SUMO-RegA_D68A and 6His-SUMO-RegA_A102S concentrations (μM) are indicated above each lane.
