Mitochondrial NADH:ubiquinone oxidoreductase (complex I) is a very large membrane protein complex with a central function in energy metabolism. Complex I from the aerobic yeast Yarrowia lipolytica… Expand
Two‐dimensional native electrophoretic analysis of respiratory supercomplexes from Yarrowia lipolytica
Mitochondria of the strictly aerobic yeast Yarrowia lipolytica contain respiratory complex I with close functional and structural similarity to the mammalian enzyme. Unlike mammalian mitochondria,… Expand
Functional Dissection of the Proton Pumping Modules of Mitochondrial Complex I
A catalytically active subcomplex of respiratory chain complex I lacks 14 of its 42 subunits yet retains half of its proton-pumping capacity, indicating that its membrane arm has two pump modules.
