Intracellular concentrations of DnaK in E. coli ATCC 25922, after incubation in BHI broth at various temperatures^a

Temp (°C)	No. of DnaK molecules/cellb	Ratio of DnaK to total proteinsc (%)
		Exptl value	Value cited in literatured
30	18,767 ± 3,044	0.63 ± 0.11	0.66
37	38,500 ± 6,056	0.98 ± 0.07	1.00
42	103,867 ± 13,735	1.60 ± 0.32	1.42

^aCells were grown until an OD₆₀₀ of 0.5 was reached. The experiments were repeated three times.

^bThe concentrations per cell were calculated with the number of cells present before the treatment.

^cTotal proteins were evaluated after sonification.

^dValues are cited by Herendeen et al. (8).
