Figure 4
(a, b) Backbone superposition of the ensemble of 20 structures calculated for reduced (a) and oxidized (b) Ec-Trx on the structure closest to the average. (c, d) Cartoon representation of the reduced (c) and oxidized (d) Ec-Trx structure closest to the average structure from the ensembles in (a) and (b), respectively, to assist reference to the structure ensembles. In (a)–(d) the 21-residue N-terminal tag has been removed for clarity; the α-helices and β-strands are colored red and blue, respectively, and the side chains of the active-site cysteines are colored yellow. |
