*RNA editing of mitochondrially encoded subunits: amino acids were changed at the listed positions as detailed. The changes were based on the reported equivalent A. thaliana RNA edits (Giegé and Brennicke, 1999; Bentolila et al., 2008) and were only made when density was unambiguously correct for the edited V. radiata amino acid in the cryoEM map.
