Abstract
Three-dimensional structures of NADH:ubiquinone oxidoreductase (or complex I) from the respiratory chain of mitochondria and bacteria have been recently studied by electron microscopy. The low-resolution structures all reveal a characteristic L shape for complex I; however, some of the differences among these structures may have important implications for the location of the functional elements of complex I, for example, the ubiquinone-binding site.
