ChrC (a) and ChrF (b) were overexpressed with carboxy-terminal 6-histidine tags in E. coli BL21 (DE3). Lane 1, DNA ladder; lane 2, whole-cell extract from uninduced cells containing pET30a expressing the proteins; lane 2, whole-cell extract from induced cells containing pET30a expressing the proteins; lane 3, purified ChrC-His6 (a) and ChrF-His6 (b) by Ni2+ nitrilotriacetic acid affinity chromatography
