P.2 2nd paragraph: "The information in Table 1 has been compiled from several sources, listed in the footnotes to the table. The compilation was guided by the article by Umbarger (ref 17), and began with the overall percent composition data of Roberts et al. (ref 13) for macromolecules. These data were then adjusted to match other information on glycogen (ref 5), lipid (ref 16), polyamines (ref 9), and stable RNA/protein/DNA ratios (ref 4)." Table contains general information on quantities of macromolecules per cell. Note 'a' beneath table: "Calculated for an average cell in a population of E. coli B/r in balanced growth at 37°C in aerobic glucose minimal medium with a mass doubling time of 40 min." See note 'a' under table for more details. See BNID 106270. For yeast cell composition of dry mass see BNID 104157 |
