Figure 2
The active-site CPYC motif in the (a) PfGrx1-SAD, (b) PfGrx1-AR1 and (c) PfGrx1-AR2 structures. The final 2Fo − Fc map is contoured at 1.5σ for PfGrx1-SAD and is contoured at 3σ for both PfGrx1-AR1 and PfGrx1-AR2. The difference Fourier (Fo − Fc) map at the 3σ level (orange) shows an alternate position of Cys29 in PfGrx1-AR2. |
