For proteins with a mitochondrial-targeting pre-sequence, residue 1 is the first residue of the mature protein 3.

^†

Known structures with high homology to the complex I subunits were identified by HHpred⁵⁵.

^‡

RMSD: root mean square deviation calculated using PDBeFOLD⁵⁹ between the structures of the subunits of B. taurus complex I and the PDB model structures.

^§

Subunit with less certain assignment.

^¶

Residue numbers are arbitrary and not assigned to the sequence.
