The secondary structure of GPx-1 consists of nine β-strands and nine α-helices with five of the helices being of the 310 form (Figure 2)[[Image:Helix310.jpg|100px|left|thumb|]]. Interestingly two of the β-strands form a parallel β-sheet (Figure 3)[[Image:Beta_sheets3.jpg|100px|right|thumb|]]. GPx-1 exhibits a thioredoxin like fold. The classic thioredoxin fold consists of a four stranded β-sheet that is surrounded by three α-helices (Figure 4)[[Image:Thioredoxin_fold.jpg|100px|left|thumb|]] (5). However the thioredoxin fold is commonly subject to the insertion of additional secondary structural elements between the second β-strand and the second α-helices (6). This is seen in GPx-1 as there is an addition of an α-helix and a β-strand between the second β-strand and the second α-helices (Figure 5)[[Image:Thioredoxin_like_fold.jpg|100px|right|thumb|]] (6). A similar insertion is found in peroxiredoxins, a different family of proteins which also catalyze the reduction of hydroperoxides(6). | The secondary structure of GPx-1 consists of nine β-strands and nine α-helices with five of the helices being of the 310 form (Figure 2)[[Image:Helix310.jpg|100px|left|thumb|]].
