Protein-disulfide isomerase (PDI), a critical enzyme responsible for oxidative protein folding
in the eukaryotic endoplasmic reticulum, is composed of four thioredoxin domains a, b, b′,
a′, and a linker x between b′ and a′. Ero1-Lα, an oxidase for human PDI (hPDI), has
been determined to have one molecular flavin adenine dinucleotide (FAD) as its prosthetic
group. Oxygen consumption assays with purified recombinant Ero1-Lα revealed that it
utilizes oxygen as a terminal electron acceptor producing one disulfide bond and one …
