Figure 7
Superposition of the structure closest to the mean for Bm-YffB (PDB entry 2kok , blue) on the crystal structure determined for E. coli ArsC (PDB entry 1id9 , magenta; Martin et al., 2001BB22) using the program SuperPose (Maiti et al., 2004BB20). The side chains of the three arginine residues in Ec-ArsC (Arg60, Arg94 and Arg107) that form a thiasahydroxyl adduct that is essential for enzymatic function are labeled and colored red. The only residue in Bm-YffB that is equivalent to those in the arginine triad of Ec-ArsC is Arg96; this side chain is colored black.
