Figure 2. Redox-dependent structural changes in AtTrx h1.
(A) HSQC spectra of oxidized (green contours) and reduced (red
contours) AtTrx h1, with cross-peaks for residues with
significant shift perturbations connected by arrows. (B)
Combined 1H/15N shift differences are plotted as a function of
AtTrx h1 sequence. (C) Ribbon diagram of AtTrx h1 NMR structure
with chemical shift perturbations indicated in green (0.25-1)
and magenta (>1). (D) Comparison of structures of AtTrx h1 and
poplar Trx h1 (PDB code 1TI3 [PDB]
), aligned over all residues using the FATCAT servfer (Ye and
Godzik 2004).
