This is a flavin adenine dinucleotide (FAD) binding domain found in Quiescin sulfhydryl oxidases (QSOX) (EC:1.8.3.2). QSOX is a multi-domain disulfide catalyst that is localized primarily to the Golgi apparatus and secreted fluids and has attracted attention due to its over-production in tumors. Structural studies indicate that the closure of the Trx1 domain over the FAD-binding site may enhance the active-site chemistry for disulfide formation [1 -3].	Domain
