Comments P.99 right column top paragraph: "To estimate the absolute membrane occupancy of these non-respiratory proteins, [investigators] (1) use data from Valgepea et al. (2013)) to determine relative abundances of non-electron transport chain proteins at each growth rate and (2) use the independent experimental observation that metabolic functions, predominantly electron transport chain, make up roughly one-third of all inner membrane proteins (primary source) (Table S1B)."
