Figure 6.

Figure 6

Surface representation of NADPH binding pocket with blue representing basic residues, red acidic residues, and white neutral residues. (A) ecTrxR structure with NADPH bound. (B) taTrxR structure with modeled NADPH. (C) ecTrxR structure with NADH modeled in the NADPH binding site. (D) taTrxR structure with NADH modeled in the NADPH binding site. The orientations shown in Figure 6 are similar to those shown in Figure 5, with the panels in Figure 6 rotated slightly to the left so that the NAD(P)H adenine rings are more clearly visible. Surface calculations were made using the APBS module in Pymol (45).
