Fig. 1: The structure of complex I from P. denitrificans.
From: Structure of the turnover-ready state of an ancestral respiratory complex I
a The 14 core subunits are shown and labelled in colour with the supernumerary subunits in grey. b The supernumerary subunits are shown and labelled in colour with transparent surfaces, with the core subunits in grey. Subunits with homologues in human CI are named using the human nomenclature; the PIMT subunit is specific to P. denitrificans. FeS clusters are shown in orange and yellow.
