Structural highlights 3rko is a 12 chain structure with sequence from Escherichia coli BL21(DE3). The December 2011 RCSB PDB Molecule of the Month feature on Complex I by David Goodsell is 10.2210/rcsb_pdb/mom_2011_12. Full crystallographic information is available from OCA.

The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.[HAMAP-Rule:MF_01456] See Also NADH-quinone oxidoreductase
