| Method |
Calculated from data in table link in ref and according to average molecular mass of amino acid in E. coli protein of 108 Da (Primary source): (108[g per mole]/Avogadro's constant[aa residues per mole]) X(number of aa residues per OD460)/(number of cells per OD460)=weight [g/cell]:(108/(6X10^23))X(5X10^17)/(2X10^8)=450X10^-15 g |
| Comments |
Out of cell dry mass of 865X10^-15 g at this doubling time. Note-according to calculation from Primary source table link average amino acid molecular mass is 109 Da, see BNID 104877. Reference table gives Protein/mass, RNA/mass, DNA/mass, cell no./mass, protein/genome, RNA/genome, origins/genome, protein/origin and more parameters at 5 different doubling times |
