Thioredoxins play key roles in the cellular response to oxidative stress. Three isoforms of thioredoxin have been identified in Saccharomyces cerevisiae : two that are cytosolic (Trx1 and Trx2) and one that is mitochondrial (Trx3). In the present work, the cytosolic form Trx1 was cloned, expressed, purified and crystallized. Crystals were obtained by the hanging‐drop vapour‐diffusion method. A data set was collected from a single crystal to 1.7 Å resolution. The crystal belongs to space group P 2 1 2 1 2 1 , with unit‐cell parameters a = 32.29, b = 46.59, c = 64.20 Å, α = β = γ = 90°.
