Figure 3. Compositional comparison of SARS-CoV-2 biomass and
host maintenance based on human lung cell protein expression. The values
on the Y‑axis of both panels are the base 2 logarithms of the ratio of
the proportion of each metabolite (amino acid or nucleotide) in the
virus biomass divided by its proportion in the host maintenance
function. The proportion of each metabolite is its stoichiometric
coefficient in the corresponding reaction (virus biomass or host
maintenance) in mmol∙gDW-1, divided by the sum of all
stoichiometric coefficients in that reaction.
