Structural comparison of VvPrx3 in reduced and oxidized states. (a) A magnified view focusing on the interactions at the C-type interface (Fig. 1[link]c; red circle) with the intermolecular disulfide bond present between Cys48 residues. The side chains involved in the hydrophobic core are shown in ball-and-stick representation. The loops in this interface are labelled La, Lb and Lc, indicating the loop connecting β3 and α2, the loop connecting β6 and β7, and the loop connecting β9 and α5, respectively. Primes are used in the labels to distinguish the protomers. (b) Structural superposition of VvPrx3 in the reduced form (green) and the disulfide-bridged (oxidized) form (blue).
