FIGURE 1.
SDS-PAGE of wt DevS642 (molecular weight 25330 Da) and H149A mutant after purification by affinity chromatography. In each lane about 0.5 μg of protein was loaded on a 12% BT Novex NuPage gel. Lane 1, SeeBlue Plus 2 prestained protein standard (7 μL); lane 2, DevS642 expressed in the presence of hemin, lane 3, H149A mutant expressed in the presence of hemin; lane 4, DevS 642 apoprotein; lane 5, H149A mutant apoprotein.
