Ratio of energy expenditure for protein polymerization to mRNA polymerization

Value 20 unitless
Organism Bacteria Escherichia coli
Reference Physiology of the Bacterial Cell: A molecular approach; Authors: Frederick Neidhardt, John Ingraham, and Moselio Schaechter; Page: 96
Comments Uses an estimate that the average mRNA is translated ~30 times. Assumes a nucleotide polymerization cost of 2 ~P, an amino acid activation and incorporation costs of 4 ~P (2~P for GTP->GDP and 2~P for ATP->ADP). And 3 bases are needed per amino acid so 30/3*4/2=20.
