From: Diversification of Quiescin sulfhydryl oxidase in a preserved framework for redox relay
The QSOX ψErv/Erv module resembles a baculovirus Erv enzyme. The structure of the H. sapiens QSOX sulfhydryl oxidase module [11] is compared with one subunit of the baculovirus Ac92 sulfhydryl oxidase dimer [22]. Helices are represented as cylinders, the FAD is in orange sticks, and the FAD-proximal redox-active disulfide is indicated in ball-and-stick format and labeled CXXC.
