Figure 1. A: Cartoon representation of the overall fold of Hyr1, colored and labeled according to the secondary structures. Cys36 thiol was highlighted as sticks and the interrupted points were colored with purple and connected with a gray dashed line. B, C: Superposition of Hyr1 (red) upon rPtGpx5 (cyan) and oPtGpx5 (gray), respectively. The helix 2 of rPtGpx5 and peroxidatic and resolving cysteine of all structures were labeled. D: Hyr1 peroxidase activity assays. Assays were performed separately for three times in the presence of Trx2, Trr1, NADPH, and H[2]O[2], with Hyr1 (filled squares), with Hyr1-Cys82Ser mutant (open triangles), without Hyr1 as a null control (filled circles). Data are expressed as the decrement of OD[340 nm] against time in minute. The error bars represent the standard deviations.
