CrpaA.01119.a.A1/TIM dimer. View of the dimer of CrpaA.01119.a.A1/TIM, which has the typical TIM-barrel fold. The active-site loop (Pro168–Ala178) is highlighted in red and is in the typical `open' conformation. Despite the open conformation of the loop, extra Fo − Fc electron density can be observed in proximity to the active site. The structure was deposited with UNK atoms as indicators for unidentified atoms (highlighted with red spheres).
