    A disintegrin and metalloprotease-17 (ADAM17) is a major sheddase responsible for the regulation of a wide range of biological processes, like cellular differentiation, regeneration, or cancer progression. Hitherto, the mechanism regulating the enzymatic activity of ADAM17 is poorly understood. Recently, protein-disulfide isomerase (PDI) was shown to interact with ADAM17 and to down-regulate its enzymatic activity. Here we demonstrate by NMR spectroscopy and tandem-mass spectrometry that PDI directly interacts with the membrane-proximal domain (MPD), a domain of ADAM17 involved in its dimerization and substrate recognition. PDI catalyzes an isomerization of disulfide bridges within the thioredoxin motif C600XXC603 of the MPD and results in a drastic structural change between an active open state and an inactive closed conformation. This conformational change of the MPD putatively acts as a molecular switch, facilitating a global reorientation of the extracellular domains in ADAM17 and regulating its shedding activity.
