Figure 6. Key Interactions Centered about Helix α2 in the
Reduced and Oxidized Forms of Xc OhrR
(A) van der Waals
contacts made by L17 in the reduced OhrR structure are shown as
dotted lines. Residues making direct and networked contacts to
L17 are shown as blue sticks. The OHP sensor cysteine residue is
shown as yellow sticks, and Y36 and Y47 are shown as red sticks.
(B) Rearrangement of the L17 hydrophobic pocket and
disorder of helix 1b upon oxidation. Residues interacting with
L17 in the reduced form are shown in their new positions in the
oxidized form. The side-chain color scheme is the same as in (A).
