Ribbon diagram depicting the secondary structure and fold of TvTrx. α-Helices are red, β-strands yellow and segments of coil green. Trp34, Cys35 and Cys38 side chains, which mark the redox centre, are presented as sticks coloured according to atomic position, where N is blue, C grey and S orange. Figs. 1, 2 and 3(a) were prepared using PyMOL (DeLano, 2002). |
