Total number of amino acids in a cell (mostly in proteins)

Range 5.6×10^8 - 2.5×10^9 Table - link Amino acids
Organism Bacteria Escherichia coli
Reference Bremer, H., Dennis, P. P. (1987) Modulation of chemical composition and other parameters of the cell by growth rate. Neidhardt, et al. eds. Escherichia coli and Salmonella typhimurium: Cellular and Molecular Biology, 1st ed. chapter 96, Table 2 pp.1530-1
Comments Depends on growth rate which affects cell size and number of genomes. Lower value for a 100 minutes cell generation time, higher value for a 24 minutes cell generation time. For 40 min generation time 1.3×10^9 amino acids per cell. All for exponentially growing cell at 37°C
