Authors: Wenguang G Liang / Juwina Wijaya / Hui Wei / Alex J Noble / Jordan M Mancl / Swansea Mo / David Lee / John V Lin King / Man Pan / Chang Liu / Carla M Koehler / Minglei Zhao / Clinton S ...Authors: Wenguang G Liang / Juwina Wijaya / Hui Wei / Alex J Noble / Jordan M Mancl / Swansea Mo / David Lee / John V Lin King / Man Pan / Chang Liu / Carla M Koehler / Minglei Zhao / Clinton S Potter / Bridget Carragher / Sheng Li / Wei-Jen Tang / Abstract: Presequence protease (PreP), a 117 kDa mitochondrial M16C metalloprotease vital for mitochondrial proteostasis, degrades presequence peptides cleaved off from nuclear-encoded proteins and other ...Presequence protease (PreP), a 117 kDa mitochondrial M16C metalloprotease vital for mitochondrial proteostasis, degrades presequence peptides cleaved off from nuclear-encoded proteins and other aggregation-prone peptides, such as amyloid β (Aβ). PreP structures have only been determined in a closed conformation; thus, the mechanisms of substrate binding and selectivity remain elusive. Here, we leverage advanced vitrification techniques to overcome the preferential denaturation of one of two ~55 kDa homologous domains of PreP caused by air-water interface adsorption. Thereby, we elucidate cryoEM structures of three apo-PreP open states along with Aβ- and citrate synthase presequence-bound PreP at 3.3-4.6 Å resolution. Together with integrative biophysical and pharmacological approaches, these structures reveal the key stages of the PreP catalytic cycle and how the binding of substrates or PreP inhibitor drives a rigid body motion of the protein for substrate binding and catalysis. Together, our studies provide key mechanistic insights into M16C metalloproteases for future therapeutic innovations. | |||||||||
