It is also implicated in many common human neurodegenerative diseases. Here, we report the first crystal structure of the entire, intact complex I (from Thermus thermophilus) at 3.3 Å resolution. The structure of the 536-kDa complex comprises 16 different subunits, with a total of 64 transmembrane helices and 9 iron-sulphur clusters. The core fold of subunit Nqo8 (ND1 in humans) is, unexpectedly, similar to a half-channel of the antiporter-like subunits. Small subunits nearby form a linked second half-channel, which completes the fourth proton-translocation pathway (present in addition to the channels in three antiporter-like subunits). The quinone-binding site is unusually long, narrow and enclosed. The quinone headgroup binds at the deep end of this chamber, near iron-sulphur cluster N2. Notably, the chamber is linked to the fourth channel by a 'funnel' of charged residues. The link continues over the entire membrane domain as a flexible central axis of charged and polar residues, and probably has a leading role in the propagation of conformational changes, aided by coupling elements. The structure suggests that a unique, out-of-the-membrane quinone-reaction chamber enables the redox energy to drive concerted long-range conformational changes in the four antiporter-like domains, resulting in translocation of four protons per cycle.","lang":"eng"}],"_id":"1978","doi":"10.1038/nature11871","author":[{"full_name":"Baradaran, Rozbeh ","first_name":"Rozbeh","last_name":"Baradaran"},{"last_name":"Berrisford","first_name":"John","full_name":"Berrisford, John M"},{"last_name":"Minhas","full_name":"Minhas, Gurdeep S","first_name":"Gurdeep"},{"last_name":"Sazanov","id":"338D39FE-F248-11E8-B48F-1D18A9856A87","first_name":"Leonid A","full_name":"Leonid Sazanov","orcid":"0000-0002-0977-7989"}],"quality_controlled":0,"title":"Crystal structure of the entire respiratory complex i"}
