| + | Disulfide bond formation in the endoplasmic reticulum by the sulfhydryl oxidase Ero1 family is thought to be accompanied by the concomitant formation of hydrogen peroxide. Since secretory cells can make substantial amounts of proteins that contain disulfide bonds, the production of this reactive oxygen species could have potentially lethal consequences. Here, we show that two human proteins, GPx7 and GPx8, labeled as secreted glutathione peroxidases, are actually endoplasmic reticulum-resident protein disulfide isomerase peroxidases. In vitro, the addition of GPx7 or GPx8 to a folding protein along with protein disulfide isomerase and peroxide enables the efficient oxidative refolding of a reduced denatured protein. Furthermore, both GPx7 and GPx8 interact with Ero1alpha in vivo, and GPx7 significantly increases oxygen consumption by Ero1alpha in vitro. Hence, GPx7 and GPx8 may represent a novel route for the productive use of peroxide produced by Ero1alpha during disulfide bond formation. | ||
