Citation | Journal: Annu Rev Biophys / Year: 2019Title: Mammalian Respiratory Complex I Through the Lens of Cryo-EM. Authors: Ahmed-Noor A Agip / James N Blaza / Justin G Fedor / Judy Hirst / ![]() Abstract: Single-particle electron cryomicroscopy (cryo-EM) has led to a revolution in structural work on mammalian respiratory complex I. Complex I (mitochondrial NADH:ubiquinone oxidoreductase), a membrane- ...Single-particle electron cryomicroscopy (cryo-EM) has led to a revolution in structural work on mammalian respiratory complex I. Complex I (mitochondrial NADH:ubiquinone oxidoreductase), a membrane-bound redox-driven proton pump, is one of the largest and most complicated enzymes in the mammalian cell. Rapid progress, following the first 5-Å resolution data on bovine complex I in 2014, has led to a model for mouse complex I at 3.3-Å resolution that contains 96% of the 8,518 residues and to the identification of different particle classes, some of which are assigned to biochemically defined states. Factors that helped improve resolution, including improvements to biochemistry, cryo-EM grid preparation, data collection strategy, and image processing, are discussed. Together with recent structural data from an ancient relative, membrane-bound hydrogenase, cryo-EM on mammalian complex I has provided new insights into the proton-pumping machinery and a foundation for understanding the enzyme's catalytic mechanism. | |||||||||

In brief, UltrAuFoil gold grids (0.6/1) were glow discharged at 20 mA for 60 sec using a EMITECH glow-discharger unit. Then, the grids were incubated in 5 mM 11-mercaptoundecyl hexaethyleneglycol (SPT-0011P6, SensoPath Technologies) in ethanol for two days under anaerobic conditions. | ||||||||||||
