ED Figure 4. Example regions of the cryoEM density map for the supernumerary subunits, and the model fitted to the map.

ED Figure 4

a) Subunit MWFE, containing one TMH. b) Subunit B14.5, containing two TMHs. The N- and C-terminal loops are not shown. c) 15 kDa subunit on the IMS face, containing a CHCH domain with two disulphide bonds. The N- and C-terminal loops are not shown. d) The seven-strand β-sheet in the 39 kDa subunit, showing the separation of the strands, and the bound nucleotide (red density) modelled as NADPH. e) Helix 1, one of the arginine-rich helices, in B22, and SDAP-β, on the matrix side of the tip of the membrane domain. Inset: the weak density attached to Ser44 in SDAP-β attributed to the attached pantetheine-4'-phosphate group (side chain of Ser44 not shown).
