Range 6800-72000 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, pp. 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 lower value is for slow division rate (100 minutes) and higher value is for fast division rate (24 minutes). See BNID 105779, 105780
