Figure 3
Dimer interaction site of Msm-TrxR with fragments shown in pink. The pocket is located between the FAD-binding domains (shades of blue) of both protomers. All fragments are located twice in the binding pocket, one from each protomer. Fragments D02 (a) and D06 (b) as examples show that the fragments are mirrored in the binding pocket and interact with both protomers (hydrogen bonds are shown as black dashed lines). |
