Baculovirus sulfhydryl oxidase complex with acetate and imidazole, showing the FAD, 3p0k Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Sulfhydryl oxidase (SOX) is a flavin-dependent enzyme which catalyzes the formation of disulfide bonds from thiol groups. The reaction involves the reduction of O2 to hydrogen peroxide[1]. Erv1p is involved in the biogenesis of Fe/S clusters[2]. ALR is a SOX augmenter of liver regeneration[3]. QSOX is a quiescin SOX. QSOX contains thioredoxin domain, helix-rich domain and FAD-binding domain Erv/ALR[4]. in Baculovirus sulfhydryl oxidase (3p0k). Water molecules are shown as red spheres. 3D structures of sulfhydryl oxidase Sulfhydryl oxidase 3D structures
