The relative cross-reactivity of poly- clonal antibodies was used to probe the conforma- tional variations at the tertiary level among ... disintegration of the iron–sulfur cluster in each of the WhiB proteins (Fig. 3C,D). Therefore, disassembly of the iron–sulfur cluster under oxidizing conditions and its stability under reducing condit...

... Furthermore, the selection is found to be dependent on selection conditions. In the ionic denaturant (guanidinium chloride) solution, nonpolar surface inter- actions were optimized, whereas at elevated temperatures variants ... computation efficient [22,27,29]. The fix of the backbone conformations could potentially prevent selection of alternative attractive structures that are slightly diff...
