Value 26300 Copies/cell Range: Table - link Copies/cell
Organism Bacteria Escherichia coli
Reference Bremer, H., Dennis, P. P. (1996) 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, 2nd ed. chapter 97, p.1559, Table 3
Method Note 'o' beneath table: "The number of ribosomes per cell was determined from values in tables 1 [ link ] and 2 [ link ] and the relationship Nr=Rc×fs×(1-ft)/(nucl./rib), where fs, ft, and nucleotides per ribosome are defined in table 1." Nr=ribosomes/cell. Rc=RNA/cell
Comments In the growth rate of 0.6 to 2.5 doublings per hour, (100min-24min doubling time), the ribosome numbers are 6800-72000, respectively. See BNID 101441
